2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	CC Mode update to 5.31.

	* progmodes/cc-subword.el: Add a dummy `c-subword-mode' for
	Emacsen which lack `define-minor-mode'.  (Currently Emacs <21.  We
	might do this function properly in the future).

	* progmodes/cc-cmds.el, cc-defs.el, cc-styles.el, cc-vars.el: New
	macros c-sentence-end and c-default-value-sentence end, to cope
	with Emacs 22's new function `sentence-end'.

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-cmds.el (c-show-syntactic-information): Solved the
	compat issue using `c-put-overlay' and `c-delete-overlay'.

	* progmodes/cc-defs.el (c-put-overlay, c-delete-overlay): New
	compat macros to handle overlays/extents.

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-fix.el: Add definitions of the macros push and pop
	(for GNU Emacs 20.4)

	* progmodes/cc-defs.el:
	(i) Load cc-fix.elc for `push' and `pop' (for GNU Emacs 20.4)

	* progmodes/cc-cmds.el (c-show-syntactic-information): change the
	highlighting mechanism so it will work in XEmacs too.

	* progmodes/cc-defs.el: Insert c-int-to-char.

	* progmodes/cc-langs.el (c-nonsymbol-token-char-list): Insert a
	call to the new macro c-int-to-char.  This solves XEmacs's
	regarding characters as different from integers.

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-fonts.el (c-make-syntactic-matcher): New internal
	helper.

	(c-cpp-matchers, c-basic-matchers-before): Use the `eval'
	construct to make the indirect face lookup work in XEmacs.

	(c-cpp-matchers): Append the negation char face to the existing
	fontification, so that the cpp face doesn't disappear.  Use
	`c-make-syntactic-matcher' to avoid negation chars in comments and
	strings.

	* progmodes/cc-fonts.el (c-negation-char-face-name): New variable
	to map to `font-lock-negation-char-face' in emacsen where it
	exists.

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-mode.el: Bind c-subword-mode to C-c C-w.

	* progmodes/cc-subword.el, cc-cmds.el, cc-mode.el: Rename
	"c-subword-move-mode" as "c-subword-mode".

	<delete> and C-c C-<delete>.  (To the c-hungry- delete functions).

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-mode.el: Added autoload directive for
	`c-subword-move-mode' for use in older emacsen.

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-mode.el:
	(i) Insert a binding for C-c C-backspace into
	c-bind-special-erase-keys which works in TTYs.
	(ii) Make sure that when file styles are used, any explicitly
	given style variables take priority over those in the style.  Do
	this by calling `hack-local-variables' a second time.

	* progmodes/cc-vars.el: Add language specific customization
	widgets for AWK to c-doc-comment-style, c-require-final-newline
	and c-default-style.  Add a defcustom for awk-mode-hook.  Give
	c-syntactic-element and c-syntactic-context doc-strings by
	directly setting their `variable-documentation' propery.  This
	allows Emacs 22.1 to read these with C-h v.

	* progmodes/cc-awk.el: Apply a tidy-up patch (from Stefan
	Monnier).

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	and C-c C-<delete>.

	(c-bind-special-erase-keys): New function for use on
	`normal-erase-is-backspace-hook' to bind C-c C-<delete> correctly.

	* progmodes/cc-cmds.el (c-hungry-delete): New function to fix
	<delete> key behavior in XEmacs according to `delete-forward-p'.
	C.f. `c-electric-delete'.

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-cmds.el (c-electric-semi&comma): Bind
	c-syntactic-context for calls to "criteria functions", for
	consistency with other calls to user functions.

	* progmodes/cc-cmds.el (c-indent-command): expunge use of
	`current-prefix-arg', since this might be the prefix arg to a
	command which calls c-indent-command as a function.  Change the
	interactive spec from "p" to "P".

	* progmodes/cc-styles.el: Amend the doc-string of c-set-style, in
	reponse to a report from Joseph Kiniry <kiniry@acm.org> that it

	c-toggle-electric-state.

	* progmodes/cc-vars.el: Make c-syntactic-indentation buffer local.

	* progmodes/cc-cmds.el: Add `c-bytecomp-defun's for
	c-\(forward\|backward\)-subword.
	(c-update-modeline): Add the new modeline flag `l' for
	`c-electric-flag'.  Make the auto-newline flag `a' dependent on
	`l'.
	(c-toggle-auto-state): Rename it to `c-toggle-auto-newline'.  Make
	the old name an alias of the new name.
	(c-toggle-electric-state): New function.

	Tidy up the coding somewhat.
	(c-electric-semi&comma, c-electric-colon, c-electric-paren):

	idea.

	* progmodes/cc-mode.el, cc-cmds.el, cc-defs.el, cc-engine.el
	(c-submode-indicators): Changed name from `c-auto-hungry-string'
	since it's now used to track another submode.

	(c-update-modeline): Converted to function and extended to check
	`c-subword-move-mode'.

	(c-forward-into-nomenclature, c-backward-into-nomenclature):
	Converted to compat aliases for `c-forward-subword' and
	`c-backward-subword'.

	* progmodes/cc-subword.el: New functions and minor mode to handle
	SillyCapsedStyleIndentifiers, contributed by Masatake YAMATO:

	(c-forward-subword, c-backward-subword, c-mark-subword,
	c-kill-subword, c-backward-kill-subword, c-transpose-subwords,

	entry for one-liner-defun.

	* progmodes/cc-defs.el: Give c-tentative-buffer-changes its own
	name in its def-edebug-spec.

	* progmodes/cc-cmds.el (c-electric-brace): Make the
	one-liner-defun clean-up work with empty-defun-braces.  o-l-d now
	compacts space before a comment, if this will make things fit on
	one line.

	Introduce an "awk" style, mainly for auto-newline and clean-ups.

	* progmodes/cc-align.el: new function c-snug-1line-defun-close

	* progmodes/cc-cmds.el: In c-electric-brace, add code for new
	clean-up one-liner-defun.

	* progmodes/cc-styles.el: Add the new "awk" style.

	* progmodes/cc-vars.el: Add description of one-liner-defun to
	c-cleanup-list's doc-string.  New user options,
	c-max-one-liner-length.  In c-default-style, set the default style
	for AWK to "awk".

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-engine.el (c-forward-label): Fixed fontification of
	macros inside labels.

	* progmodes/cc-engine.el (c-looking-at-bos): Obsoleted in favor of
	`c-at-statement-start-p' and `c-at-expression-start-p'.

	* progmodes/cc-defs.el (c-tnt-chng-record-state): Don't signal an
	error if the mark isn't set.

	* progmodes/cc-engine.el (c-guess-continued-construct,
	c-guess-basic-syntax): Use `c-forward-decl-or-cast-1' to more
	accurately detect functions inside functions.

	* progmodes/cc-engine.el (c-at-expression-start-p): New function
	like `c-at-statement-start-p' that additionally recognizes commas
	and expression parentheses as delimiters.

	* progmodes/cc-engine.el (c-looking-at-inexpr-block): Added flag
	to avoid heuristics that doesn't work for unclosed blocks.

	(c-at-statement-start-p): New function.

	* progmodes/cc-engine.el, cc-fonts.el: Fixes in handling of
	Objective-C directives, e.g. directives spanning lines should work
	reasonably well now.

	(c-put-c-type-property, c-clear-c-type-property): New helpers.

	(c-forward-objc-directive): New function to move over any ObjC
	directive.

	(c-just-after-func-arglist-p, c-guess-basic-syntax,
	c-basic-matchers-before): Use it.

	(c-font-lock-objc-iip-decl): Removed.

	* progmodes/cc-engine.el (c-guess-basic-syntax): Some improvement
	in the template arglist recognition.

	* progmodes/cc-styles.el (c-style-alist): Fixed several
	inconsistencies in the Whitesmith style.

	* progmodes/cc-align.el (c-lineup-after-whitesmith-blocks): New
	lineup function to get lines after Whitesmith style blocks
	correctly indented.

	(c-lineup-whitesmith-in-block): Backed out the compensation for
	opening parens since it's done using `add' lists in the style
	definition instead.  Don't use the anchor position since it varies
	too much between the syntactic symbols. :P

	* progmodes/cc-vars.el (c-valid-offset): Updated.

	* progmodes/cc-engine.el (c-evaluate-offset): Extended to handle
	lists where the offsets are combined according to several
	different methods: `first', `min', `max', and `add'.  Report
	offset evaluation errors with `c-benign-error' so that some kind
	of reindentation still is done.

	* progmodes/cc-engine.el (c-guess-basic-syntax): Anchor
	`arglist-intro' the same way as `arglist-cont-nonempty' and
	`arglist-close'.

	* progmodes/cc-engine.el (c-guess-basic-syntax): Fixed similar
	situations for `arglist-cont-nonempty' and `arglist-close'.

	* progmodes/cc-langs.el (c-opt-identifier-concat-key-depth): New
	constant.

	* progmodes/cc-defs.el: Use `cc-bytecomp-fboundp' and
	cc-bytecomp-boundp' in a number of places.

	* progmodes/cc-engine.el (c-beginning-of-statement-1): Fixed a
	macro related issue.

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-awk.el: Change the terminology of regexps: A char
	list is now
	[asdf], a char class [:alpha:].  Include code for char classes.
	Set c-awk-NL-prop on lines ending in open strings.  (Bug fix.)
	Add character classes (e.g. "[:alpha:]") into AWK Mode's regexps.

	Remove (nearly all of) the cruft associated with AWK Mode's former
	concept of "virtual semicolons":

	Adapt c-beginning-of-statement, c-end-of-statement (together with
	subfunctions) to use the new notion of "virtual semicolon" in
	place of the old awkward special handling for AWK.  There remains
	much cruft in cc-awk.el, cc-cmds.el and cc-engine.el to clear out.
	* progmodes/cc-cmds.el:
	(c-ascertain-adjacent-literal): In the backwards direction, now
	recognises AWK regexp delimiters as string delimiters.
	(c-after-statement-terminator-p): Adapt for virtual semicolons;
	check more rigorously for "end of macro".
	(c-back-over-illiterals, c-forward-over-illiterals): Adapt for
	virtual semicolons;
	(c-beginning-of-statement): Adapt for virtual semicolons; Separate
	out the code for forward movement into ...
	(c-end-of-statement): Now contains the code for forward movement,
	adapted for virtual semicolons.

	* progmodes/cc-engine.el:
	(c-ws*-string-limit-regexp): new regexp.
	(c-forward-single-comment, c-backward-single-comment): Comment out
	the (now redundant) "special" AWK stuff.

	* progmodes/cc-styles.el, cc-vars.el: Change the settings of
	c-string-par-start, c-string-par-separate to be more like Text
	Mode than Fundamental Mode.

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-fonts.el (c-font-lock-declarations): Always narrow
	to the fontified region so that fontification doesn't occur
	outside it
	(could happen e.g. when fontifying a line with an unfinished
	declaration).

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-awk.el: Regexps for analysing AWK code have been
	moved to near the start of the file.  ^L now separate sections of
	the file.  New defconsts: c-awk-non-eol-esc-pair-re,
	c-awk-blank-or-comment-line-re,
	c-awk-one-line-possibly-open-string-re,
	c-awk-regexp-one-line-possibly-open-char-class-re,
	c-awk-one-line-possibly-open-regexp-re,
	c-awk-one-line-non-syn-ws*-re.  New functions: c-awk-at-vsemi-p,
	c-awk-vsemi-status-unknown-p.

	Amend the concept of "virtual semicolons" (in the indentation
	engine) for languages like AWK, such that they are now
	conceptually attached to end of the last token of a statement, not
	the end of the line.  (In AWK Mode, however, the pertinent text
	property is still physically set on the EOL.)  Remove the specific
	tests for awk-mode, thus facilitating the introduction of other
	language modes where EOLs can end statements.  (Note: The
	funtionality in cc-cmds.el, specifically
	c-beginning/end-of-statement has yet to be amended.)

	* progmodes/cc-defs.el: New macros c-at-vsemi-p,
	c-vsemi-status-unknown-p.

	* progmodes/cc-langs.el: Added `#' into AWK Mode's value of
	c-stmt-delim-chars.  New c-lang-defvars: c-at-vsemi-p-fn,
	c-vsemi-status-unknown-p-fn (in a new page).

	* progmodes/cc-engine.el: In c-beginning-of-statement-1,
	c-crosses-statement-barrier-p, c-guess-basic-syntax, replace
	numerous awkward forms like
	(if (c-major-mode-is 'awk-mode) (c-awk-prev-line-incomplete-p))
	with
	(c-at-vsemi-p).  Fix a few typos.  In c-guess-basic-syntax, new
	variable before-ws-ip, the place just after char-before-ip
	appears.

	* progmodes/cc-mode.el: Fix what's almost a semantic ambiguity in
	a comment.

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-cmds.el (c-electric-brace): Cleaned up using
	`c-tentative-buffer-changes'.

	* progmodes/cc-defs.el (c-region-is-active-p): Simplified and
	converted to macro to choose between Emacs and XEmacs at compile
	time.

	(c-set-region-active): New set counterpart to
	`c-region-is-active-p'.

	(c-tentative-buffer-changes): New macro to handle temporary buffer
	changes in a convenient way.

	(c-tnt-chng-record-state, c-tnt-chng-cleanup): Internal helpers
	for `c-tentative-buffer-changes'.

	* progmodes/cc-engine.el (c-looking-at-inexpr-block): Tightened up
	the checks for paren sexps between the point and the keyword, to
	avoid some false alarms.

	* progmodes/cc-engine.el, cc-langs.el (c-looking-at-inexpr-block):
	Fixed a situation where an error could be thrown for unbalanced
	parens.  Changed to make use of c-keyword-member' to avoid some
	repeated regexp matches.

	(c-opt-lambda-key, c-opt-inexpr-block-key,
	c-opt-inexpr-class-key): These language variable are no longer
	necessary.

	(c-block-stmt-kwds): New language constant used by
	c-looking-at-inexpr-block'.

	(c-guess-basic-syntax): Removed an optional check that looked at
	the existence of the now removed language variables.

	* progmodes/cc-engine.el (c-fdoc-shift-type-backward,
	c-forward-decl-or-cast-1): Fixed invalid recognition of C++ style
	object instantiation expressions as declarations in some contexts.
	This bug only affected languages where the declarator can't be
	enclosed in parentheses.

	* progmodes/cc-styles.el (c-style-alist): Fixed the GNU style to
	insert newlines before and after substatement braces.

	* progmodes/cc-engine.el: Improved the heuristics for recognizing
	function declaration headers and the handling of C++ style member
	init lists.

	(c-just-after-func-arglist-p): Rewritten to use
	`c-forward-decl-or-cast-1'.  Now behaves a bit differently too.

	(c-beginning-of-member-init-list): Removed since it isn't used
	anymore.

	(c-guess-basic-syntax): Case 5B adapted for the new
	`c-just-after-func-arglist-p'.  Cases 5B.1 and 5B.3 merged.  Cases
	5D.1 and 5D.2 removed since they aren't trigged anymore (case 5B.1
	covers all cases now).

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-cmds.el, cc-styles.el, cc-vars.el: New variables
	c-string-par-start/separate c-sentence-end-with-esc-eol,
	initialised in c-setup-paragraph-variables, used in string
	scanning subroutines of c-beginning-of-statement.

	* progmodes/cc-cmds.el (c-electric-brace): don't delete a comment
	which precedes the newly inserted `{'.

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-engine.el, cc-langs.el: Rewrote the recognition
	function for declaration level blocks.  It should now cope with
	templates better and also be a lot more comprehensible.

	(c-looking-at-decl-block): The new function.

	(c-search-uplist-for-classkey): The old one.  It's now a wrapper
	for compatibility.

	(c-add-class-syntax, c-guess-continued-construct,
	c-guess-basic-syntax): Adapted for `c-looking-at-decl-block'.

	(c-decl-block-key): Changed to tell apart ambiguous and
	unambiguous keywords.  Pike specials are now handled directly in
	the code instead.

	(c-block-prefix-disallowed-chars, c-block-prefix-charset): New
	language constants and variables to make the backward skip in
	`c-looking-at-decl-block' as tight as possible.

	(c-nonsymbol-token-char-list): New language constant.

	* progmodes/cc-engine.el (c-backward-<>-arglist): New function to
	find balanced template arglists backwards.

	* progmodes/cc-defs.el (c-make-bare-char-alt): New helper for
	making char classes for `c-syntactic-skip-backward'.

	* progmodes/cc-engine.el (c-guess-basic-syntax): Simplified case
	16D - can't be a class-close at that point.

	* progmodes/cc-engine.el (c-guess-basic-syntax,
	c-add-class-syntax): Don't narrow out the enclosing declaration
	level.  This makes everything a lot easier, and it was actually
	only four small places that needed it to work.  Some places that
	previously did `widen' are removed now, which has the effect that
	`c-guess-basic-syntax' never will look at things outside the
	current narrowment now.  The anchor position for `topmost-intro'
	is affected by this, but it was so bogus it was basically useless
	before, and now it's equally bogus but in a slightly different
	way.

	(c-narrow-out-enclosing-class): Gone.

	(c-most-enclosing-brace, c-least-enclosing-brace): Don't filter to
	the narrowed region.

	(c-least-enclosing-brace): Removed silly optional argument.

	* progmodes/cc-engine.el (c-beginning-of-decl-1): Fixed bug where
	the point could be left directly after an open paren when finding
	the beginning of the first decl in the block.

	* progmodes/cc-engine.el, cc-fonts.el (c-forward-keyword-clause):
	Specify which submatch to use.

	(c-decl-start-re): No no longer any need for special treatment of
	ObjC due to the above.

	(c-other-block-decl-kwds): Handle "extern" in ObjC too since it
	presumably follows C in that regard.

	* progmodes/cc-langs.el (c-identifier-ops, c-after-id-concat-ops):
	New language constants to specify operator tokens inside
	identifiers in a more high level way.

	(c-opt-identifier-prefix-key): New internal language constant.

	(c-opt-identifier-concat-key, c-opt-after-id-concat-key,
	c-identifier-start, c-identifier-key): Now completely calculated
	from other constants.

	(c-identifier-last-sym-match): Decommissioned since it's no longer
	used.

	(c-operators): Use `c-identifier-ops'.  Documented
	`postfix-if-paren'.

	* progmodes/cc-engine.el (c-forward-name): Removed the
	optimization when c-identifier-key is equal to c-symbol-key since
	it doesn't work in byte compiled files.  Don't record empty
	regions as identifiers.

	* progmodes/cc-langs.el (c-filter-ops): New helper function to
	simplify access to `c-operators' and its likes.

	(c-operator-list, c-all-op-syntax-tokens,
	c-nonsymbol-token-regexp, c-<>-multichar-token-regexp,
	c-<-op-cont-regexp, c->-op-cont-regexp, c-expr-kwds,
	c-primary-expr-regexp, c-cast-parens): Use it.

	* progmodes/cc-defs.el (c-lang-const): Fixes to allow use without
	an explicit language in functions.

	* progmodes/cc-defs.el (c-make-keywords-re): Added an appendable
	variant of adornment.

	* progmodes/cc-langs.el (c-any-class-key): Removed unused language
	variable.

	(c-type-decl-prefix-key): Removed some now unnecessary cruft from
	the Pike value.

	* progmodes/cc-engine.el (c-on-identifier,
	c-simple-skip-symbol-backward): Small fix for handling "-"
	correctly in `skip-chars-backward'.  Affected the operator lfun
	syntax in Pike.

	* progmodes/cc-langs.el (c-make-init-lang-vars-fun): Disabled the
	diagnostic message about precompiled language vars not being used.

	* progmodes/cc-langs.el (c-paren-nontype-kwds): The GCC keyword
	"__attribute__" is followed by a parenthesis.

	(c-type-start-kwds, c-prefix-spec-kwds, c-prefix-spec-kwds-re,
	c-specifier-key, c-not-decl-init-keywords): Some cleanup using new
	language constants `c-type-start-kwds' and `c-prefix-spec-kwds'.

	* progmodes/cc-fonts.el, cc-langs.el, cc-engine.el: Internal
	cleanups to properly detect the declared identifiers in various
	declarations.

	(c-decl-start-kwds): New language constant to recognize
	declarations that can start anywhere.  Used for class declarations
	in Pike.

	(c-specifier-key, c-not-decl-init-keywords,
	c-decl-prefix-or-start-re, c-find-decl-prefix-search,
	c-find-decl-spots): Implement `c-decl-start-kwds'.

	(c-other-decl-kwds, c-postfix-decl-spec-kwds, c-decl-hangon-kwds,
	c-decl-hangon-key, c-forward-decl-or-cast-1): Separated the
	handling of the compiler specific extension keywords into a new
	language constant `c-decl-hangon-kwds' that defines keyword
	clauses to be ignored in declarations.

	(c-forward-id-comma-list, c-forward-keyword-clause): Don't skip
	past unrecognized tokens when handling `c-colon-type-list-kwds'.
	Necessary to stop at the declared identifier in e.g. IDL valuetype
	declarations.

	(c-typedef-decl-kwds, c-typeless-decl-kwds, c-type-list-kwds,
	c-prefix-spec-kwds-re, c-postfix-spec-kwds,
	c-after-suffixed-type-decl-key, c-opt-postfix-decl-spec-key,
	c-forward-decl-or-cast-1): Recognize the declared identifier in
	class and enum declarations as such and not as part of the type.

	(c-forward-decl-or-cast-1, c-forward-label): Relaxed the
	interpretation of PRECEDING-TOKEN-END when there's no preceding
	token.

	(c-forward-decl-or-cast-1): Don't disregard sure signs of
	declarations when there's some syntax error later on.

	(c-complex-decl-matchers): Did away with a reference to
	`c-specifier-key'.

	* progmodes/cc-engine.el (c-maybe-labelp): Provide no default
	value - this variable is always dynamically bound.

	* progmodes/cc-engine.el, cc-fonts.el, cc-langs.el, cc-menus.el,
	cc-mode.el, cc-styles.el, cc-vars.el, cc-align.el, cc-awk.el,
	cc-cmds.el, cc-defs.el: Changed the policy for marking up
	functions that might do hidden buffer changes: All such internal
	functions are now marked instead of those that don't.

	(c-beginning-of-macro, c-end-of-macro, c-(forward|backward)-comments,
	c-(forward|backward)-single-comment, c-parse-state, c-on-identifier,
	c-(fast-|slow-|)in-literal, c-literal-limits, c-collect-line-comments,
	c-literal-type): Allow these functions to make hidden buffer changes,
	so that they are free to use text property caching later on.

	(c-electric-backspace, c-electric-delete-forward, c-electric-pound,
	c-electric-brace, c-electric-slash, c-electric-star,
	c-electric-semi&comma, c-electric-colon, c-electric-lt-gt,
	c-electric-paren, c-electric-continued-statement, c-indent-command,
	c-indent-region, c-mask-paragraph, c-indent-new-comment-line,
	c-context-line-break): Added `c-save-buffer-state' calls to comply
	with the changed semantics of the functions above.

	* progmodes/cc-engine.el (c-beginning-of-statement-1): Fixed a bug
	when macros occur in obscure places.  Optimized the sexp movement
	a bit.

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	Enhancements for c-beginning-of-statement to work in AWK Mode:

	* progmodes/cc-awk.el: Supersede c-awk-NL-prop value `;'
	(completed statement) with `}' (statement completed by closing
	brace or semicolon) and `$' (statement completed by EOL).

	(c-awk-virtual-semicolon-ends-prev-line-p,
	c-awk-virtual-semicolon-ends-line-p,
	c-awk-skip-semantic-ws-forward, c-awk-skip-semantic-ws-backward,
	c-awk-at-statement-end-p): new functions

	* progmodes/cc-cmds.el: Simplify the structure of functions
	c-forward-over-illiterals, c-back-over-illiterals.  Enhance these
	two functions and c-beginning-of-statement to handle AWK Mode.

	* progmodes/cc-engine.el: Enhance c-forward-single-comment,
	c-backward-single-comment for AWK mode.  Attempt to clarify their
	doc-strings.

	* progmodes/cc-mode.el: Put M-a and M-e into awk-mode-map.

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-engine.el, cc-fonts.el, cc-langs.el: Cleaned up the
	label handling.  Labels are now recognized in a uniform and more
	robust way, regardless of context.  Text properties are put on all
	labels to recognize the following declarations better.  Multiword
	labels are handled both in indentation and fontification for the
	benefit of language extensions like Qt.  For consistency, keywords
	in labels are now fontified with the label face instead.  That
	also applies to "case" and "default".

	(c-beginning-of-statement-1): Fixed some bugs in the label
	handling.  Disregard `c-nonlabel-token-key' in labels that begin
	with `c-label-kwds'.

	(c-find-decl-spots): Support that the callback adds more
	`c-decl-end' spots to find.

	(c-forward-decl-or-cast-1): Don't treat a list of plain
	identifiers followed by a colon as a declaration.

	(c-forward-label): New function to recognize labels.

	(c-guess-basic-syntax): Replaced uses of `c-label-key' with
	`c-forward-label'.  Moved the label recognition cases (14 and 15)
	earlier since they aren't so context sensitive now.  Handle labels
	on the top level gracefully.  Moved access label recognition to
	the generic label case (CASE 15) - removed CASE 5E.

	(c-font-lock-declarations): Added recognition of labels in the
	same round since we need to handle labels in parallell with other
	declarations to recognize both accurately.  It should also improve
	speed.

	(c-simple-decl-matchers, c-basic-matchers-after): Moved
	`c-font-lock-labels' so that it only is used on decoration level 2
	since `c-font-lock-declarations' handles it otherwise.

	(c-complex-decl-matchers): Removed the simplistic recognition of
	access labels.

	(c-decl-prefix-re): Removed the kludges that was necessary to cope
	with labels earlier.

	(c-decl-start-re): New language variable to make
	`c-font-lock-declarations' stop for the special protection labels

	(c-label-key): Removed since it's no longer used.

	(c-recognize-colon-labels, c-label-prefix-re): New language
	constants to support recognition of generic colon-terminated
	labels.

	(c-type-decl-end-used): `c-decl-end' is now used whenever there
	are colon terminated labels.

	* progmodes/cc-align.el (c-lineup-arglist): Fixed bug when the
	first argument starts with a special brace list.

	* progmodes/cc-engine.el, cc-fonts.el (c-forward-decl-or-cast-1,
	c-font-lock-declarations): Broke out the declaration and cast
	recognition from `c-font-lock-declarations' to a new function, so
	that it can be used in the indentation engine.

	* progmodes/cc-engine.el (c-find-decl-spots): Fixed bug in backing
	up to the start of the literal.  Fixed bug with the point on the
	wrong side of the search limit that could happen when the start
	position is inside a literal.

	* progmodes/cc-engine.el (c-parse-state,
	c-invalidate-state-cache): Modified the use of `c-state-cache-end'
	so that it's kept a little bit back to increase the hit rate.

	(c-parse-state): Changed the macro handling and fixed some
	glitches.  Macro context is checked more often than necessary now,
	but otoh less garbage conses are generated.

	* progmodes/cc-engine.el (c-parse-state,
	c-invalidate-state-cache): Cache the last position where
	`c-state-cache' applies.  This can speed up refontification quite
	a bit in blocks where there are many non-brace parens before the
	point.

	(c-state-cache-end): New variable for this.

	(c-guess-basic-syntax, c-debug-parse-state): Adapted for the new
	cache variable.

	* progmodes/cc-engine.el (c-find-decl-spots): Take more care to
	get close initial continue positions when the start position is
	inside a literal or macro.  Do not call the callback for spots
	before the start position (which can happen e.g. for `c-decl-end'
	spots inside comments).  Optimize better in special cases when the
	region is a single line inside a literal or macro (typically when
	the current line is refontified).

	* progmodes/cc-engine.el (c-guess-basic-syntax): Simplified calls
	to `c-add-stmt-syntax' - there's no need to explicitly whack off
	entries from the paren state.

	* progmodes/cc-engine.el (c-add-stmt-syntax): Narrowed down the
	special case for "else if" clauses.

	* progmodes/cc-engine.el (c-looking-at-inexpr-block,
	c-add-stmt-syntax): Use `c-recognize-paren-inexpr-blocks'.

	* progmodes/cc-langs.el (c-recognize-paren-inexpr-blocks): New
	language variable to recognize the gcc extension with statement
	blocks inside expressions.

	* progmodes/cc-engine.el (c-add-stmt-syntax): Restructured to make
	it somewhat more comprehensible.  The argument AT-BLOCK-START is
	no longer used and hence removed.

	(c-guess-continued-construct, c-guess-basic-syntax): Updated calls
	to `c-add-stmt-syntax'.

	* progmodes/cc-engine.el (c-backward-to-decl-anchor): Use
	`c-beginning-of-statement-1' instead of duplicating parts of it.
	This fixes bogus label recognition.

	* progmodes/cc-engine.el (c-add-type, c-check-type,
	c-forward-name, c-forward-type): Improved storage of template
	types in `c-found-types' so that they can be recognized better.

	(c-syntactic-content): Added option to skip past nested parens.

	* progmodes/cc-engine.el (c-forward-name): Set
	`c-last-identifier-range' all the time.  It's less work that way.
	Handle that there might not be an identifier to store in
	`c-last-identifier-range'.

	(c-forward-type): Handle that `c-last-identifier-range' might be
	nil from `c-forward-name'.

	* progmodes/cc-defs.el: (c-safe-scan-lists,
	c-(go-)?(up|down)-list-(forward|backward)): Added limit arguments.

	* progmodes/cc-defs.el (c-save-buffer-state): Use `unwind-protect'
	to work even if the form fails.

	* progmodes/cc-engine.el (c-parse-state): Speedup when moving far
	down in a large file in one go.

	(c-get-fallback-start-pos): New helper function for
	`c-parse-state'.

	* progmodes/cc-align.el (c-lineup-assignments): New lineup
	function which is like `c-lineup-math' but returns nil instead of
	`c-basic-offset' when it doesn't match.

	(c-lineup-math): Changed to use `c-lineup-assignments'.

2005-12-08  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* progmodes/cc-cmds.el: Fix some bugs in subfunctions of
	c-beginning-of-statement.  New subfunctions
	c-in-comment-line-prefix-p, c-narrow-to-comment-innards.

2005-12-08  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* progmodes/cc-fonts.el, cc-langs.el: Use `c-simple-ws' instead of
	hardcoded char classes whereever possible.  Changed a couple of
	places to use skip by syntax instead of skip by char class.

	* progmodes/cc-langs.el (c-unterminated-block-comment-regexp):
	Fixed a bug in the regexp that caused extreme backtracking.

	* progmodes/cc-langs.el (c-block-comment-starter,
	c-block-comment-ender): New language constants to specify in a
	single place how block comments look.

	(c-comment-start-regexp, c-block-comment-start-regexp,
	comment-start, comment-end, comment-start-skip,
	c-syntactic-ws-start, c-syntactic-ws-end, c-nonwhite-syntactic-ws,
	c-syntactic-ws, c-nonempty-syntactic-ws,
	c-single-line-syntactic-ws, c-syntactic-eol): Now built from
	`c-line-comment-starter', `c-block-comment-starter' and
	`c-block-comment-ender'.

	(c-block-comment-regexp, c-unterminated-block-comment-regexp): New
	language constants to break up things a bit.

	(c-simple-ws): New language constant for simple whitespace.

	* progmodes/cc-defs.el (c-concat-separated): New convenience
	function.

	* progmodes/cc-defs.el (c-make-keywords-re): Added kludge for bug
	in `regexp-opt' in Emacs 20 and XEmacs when strings contain
	newlines.  Allow and ignore nil elements in the list.
