* src/xterm.c (x_set_window_size):

do_pending_window_change calls after their stupid removal on
2015-08-31.

* src/w32fns.c (deliver_wm_chars): If the reported character is
ASCII, AND Meta modifier is a candidate, behave as if Meta is
present, i.e. fall back to the legacy code.  (Bug#23251)

* doc/emacs/help.texi (Help Mode): Document and index
'help-go-forward'.  (Bug#23323)

This reverts commit c93ae7a1.

This reverts commit 10597c97.

This reverts commit 33bef6e9.

* doc/emacs/dired.texi (Marks vs Flags): Clarify that for files
visited in buffers, 'dired-mark-files-containing-regexp' searches
the buffer rather than the file on disk.  (Bug#22694)

* lisp/dired.el (dired-mark-files-containing-regexp): Clarify that
for files visited in buffers, 'dired-mark-files-containing-regexp'
searches the buffer rather than the file on disk.  (Bug#22694)

* lisp/tmm.el (tmm-prompt): Don't reverse 'tmm-km-list' right at the
beginning; instead, pass a reversed copy to 'tmm--completion-table'.
(Bug#23309)
(tmm-menubar): Fix an off-by-one error in determining the menu
item when the function is called with a non-nil 'x-position'
argument.

* lisp/obsolete/vc-mcvs.el: Remove the file (bug#20475).

* lisp/vc/log-view.el (log-view-extract-comment): Remove the MCVS
reference.

* doc/misc/efaq-w32.texi (Version control): Same.

* lisp/autorevert.el (auto-revert-handler): Ignore errors
coming from `revert-buffer'.  (Bug#23276)

* lisp/progmodes/vhdl-mode.el (vhdl-version, vhdl-time-stamp): Update.
(vhdl-mode): No longer set comment-padding.
(vhdl-begin-p): Handle missing space between keyword and parenthesis.
(vhdl-beginning-of-statement-1): Fix indentation for "else generate".
(vhdl-template-else, vhdl-template-elsif): Support generate statement.
(vhdl-re-search-forward, vhdl-re-search-backward): Save match data.

* configure.ac: Use proper Autoconf parenthesization in
recent HAVE_MODULES patch.  Although this doesn’t fix any bugs,
the previous syntax was confusing.

* src/indent.c (Fvertical_motion): Pacify --enable-gcc-warnings
when using the April 6 Fedora patch to GCC.

* lisp/progmodes/sh-script.el (sh-mode-hook): Add
sh-electric-here-document-mode as an option and the default value.
(sh-mode): Mention sh-mode-hook in docstring.
(sh-mode): Remove sh-electric-here-document-mode invocation.

lisp/rect.el (rectangle--string-preview): Only create a preview if
rectangle-preview is non-nil (Bug#23248).

* lisp/rect.el (rectangle--string-preview):
(rectangle--highlight-for-redisplay): Replace 'region with
'rectangle-preview (Bug#23248).

* lisp/emacs-lisp/check-declare.el (check-declare-directory): Use
'grep-find-program', not 'find-program'.

* lisp/info-look.el: Add cl.info lookup to emacs-lisp-mode related
manuals.  (Bug#23289)

* lisp/window.el (window-max-chars-per-line): Account for
'left-fringe-width' and 'right-fringe-width' variables.

* doc/lispref/windows.texi (Window Sizes): Document the effect on
window text width when setting the width of one or both fringes to
zero.
* doc/emacs/display.texi (Fringes): Document the effect on window
text width when setting the width of one or both fringes to zero.
(Bug#22891)

* lisp/term.el (ansi-term): Force L2R 'bidi-paragraph-direction'.
(Bug#20611)

* lisp/international/mule.el (set-keyboard-coding-system): Treat
'raw-text' as another coding type that requires 8-bit characters.
* lisp/xt-mouse.el (xterm-mouse--read-coordinate): Use 'no-conversion'
instead of 'latin-1'.

* src/w32heap.c (mmap_realloc): Only attempt extending a region if
the following region has the same allocation base.  Also, use the
original allocation base and enlarged size to commit reserved
memory, to ensure that the allocation base stays at its original
value.  This fixes several hard-to-debug problems whereby part of
buffer text was overwritten with binary nulls, because
mmap_realloc copied only part of buffer text when extending it.

http://lists.gnu.org/archive/html/emacs-devel/2016-04/msg00325.html
and http://debbugs.gnu.org/cgi/bugreport.cgi?bug=23223#55 for two
examples of the related problems.

* lisp/vc/vc-hooks.el (vc-state, vc-working-revision):
Use `vc-backend' instead of `vc-responsible-backend'.  (Bug#20637)

* test/automated/vc-tests.el (vc-test--state)
(vc-test--working-revision): Deactivate now failing checks.

Problem reported by Clément Pit--Claudel (Bug#23254).
* src/doc.c: Include intervals.h.
(Fsubstitute_command_keys): If the only substitutions are for
quotes, copy the source string’s text properties too, since no
substring lengths have changed.

* lisp/cedet/semantic/symref/grep.el
(semantic-symref-filepattern-alist):
Add entry for lisp-interaction-mode
(http://debbugs.gnu.org/cgi/bugreport.cgi?bug=23223#47)

* lisp/progmodes/xref.el (xref-collect-references): Instead of
calling `semantic-symref-find-references-by-name', use
`semantic-symref-instantiate' and `semantic-symref-perform-search'
directly.  Ask for `line-and-text' results (bug#23223).
(xref-collect-matches): Include the line text in the "hit"
structure.
(xref--convert-hits): New function, split off from
`xref-collect-references' and `xref-collect-matches', to convert
"hits" to xref instance list.  Create a temporary buffer here, to
use it for post-processing all hit lines.
(xref--collect-matches): Use a different approach for non-visited
files.  Insert the line text into the temp buffer, apply the
file's major mode the best we can without reading its whole
contents, syntax-propertize, and search in the result.
(xref--collect-matches-1): Extract, to handle the common logic
between two cases.
(xref--find-buffer-visiting): New function, a wrapper around
`find-buffer-visiting' to amortize its cost.

* lisp/cedet/semantic/symref/idutils.el
(semantic-symref-idutils--line-re): New constant.
(semantic-symref-parse-tool-output-one-line): Support result type
`line-and-text'.

* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep--line-re)
(semantic-symref-parse-tool-output-one-line): Same.

* lisp/cedet/semantic/symref/cscope.el
(semantic-symref-cscope--line-re)
(semantic-symref-parse-tool-output-one-line): Same.

* lisp/cedet/semantic/symref/global.el
(semantic-symref-global--line-re)
(semantic-symref-parse-tool-output-one-line): Same.

This reverts commit c23c965b.

* doc/lispref/os.texi (Time Zone Rules):
New section, mostly with material moved here from other sections.
* doc/emacs/cmdargs.texi (General Variables):
* doc/lispref/os.texi (Time Conversion, Time Parsing):
Xref new section.

* src/editfns.c (Fformat_time_string, Fdecode_time)
(Fencode_time, Fcurrent_time_string, Fcurrent_time_zone)
(Fset_time_zone_rule):
When documenting time zone rule strings, mention the TZ
environment variable in preference to mentioning the
sort-of-internal function set-time-zone-rule.

 * lisp/emacs-lisp/autoload (autoload-find-generated-file): Suppress
   backups in newly created file.

  (autoload-ensure-default-file): Function split into two.
  (autoload-ensure-file-writeable): New function from split.

  (Bug#23203)

* src/macfont.m (macfont_list): Don't use color bitmap fonts.

It’s a proper noun.
* lisp/vc/add-log.el (add-log-time-zone-rule): Also, fix typo by
mentioning ‘format-time-string’ instead of ‘set-time-zone-rule’.
