ChangeLog

2012-05-15  Stefan Monnier  <monnier@iro.umontreal.ca>

	* lread.c (init_obarray): Declare Qt and Qnil as special.

2012-05-14  Glenn Morris  <rgm@gnu.org>

	* nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
	Put "libexec" before "bin", for the sake of init_callproc_1.

2012-05-14  Paul Eggert  <eggert@cs.ucla.edu>

	* keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

	* unexaix.c: Port to more-recent AIX compilers.
	(report_error, report_error_1, make_hdr, copy_sym)
	(mark_x, adjust_lnnoptrs, unrelocate_symbols):
	Make arguments const char *, not char *, to avoid violations of C
	standard and to fix some AIX warnings reported by Gilles Pion.

2012-05-14  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
	already have overlays loaded.
	(handle_single_display_spec): Before returning without displaying
	fringe bitmap, synchronize the bidi iterator with the main display
	iterator, by calling iterate_out_of_display_property.
	(iterate_out_of_display_property): Detect buffer iteration by
	testing that it->string is a Lisp string.
	(get_next_display_element): When the current object is exhausted,
	and there's something on it->stack, call set_iterator_to_next to
	proceed with what's on the stack, instead of returning zero.
	(set_iterator_to_next): If called at the end of a Lisp string,
	proceed to consider_string_end without incrementing string
	position.  Don't increment display vector index past the end of
	the display vector.  (Bug#11417)
	(pos_visible_p): Don't report a position visible when move_it_to
	stopped at the last line of window, which happens to be scanned
	backwards by the bidi iteration.  (Bug#11464)

2012-05-14  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (handle_single_display_spec): Return 1 for left-margin
	and right-margin display specs even if the spec is invalid or we
	are on a TTY, and thus unable to display on the fringes.  That's
	because the text with the property will not be displayed anyway,
	so we need to signal to the caller that this is a "replacing"
	display spec.  This fixes display when the spec is invalid or we
	are on a TTY.

2012-05-14  Paul Eggert  <eggert@cs.ucla.edu>

	* unexaix.c (make_hdr): Fix typo in prototype.
	This bug broke the build on AIX.  Problem reported by Gilles Pion.

2012-05-14  Michael Albinus  <michael.albinus@gmx.de>

	* keyboard.c (kbd_buffer_get_event): Read special events also in
	batch mode.  (Bug#11415)

2012-05-12  Glenn Morris  <rgm@gnu.org>

	* ns.mk: Update for ns_appbindir no longer having trailing "/".

2012-05-12  Eli Zaretskii  <eliz@gnu.org>

	* lisp.mk (lisp): Add newcomment.elc.

2012-05-12  Glenn Morris  <rgm@gnu.org>

	* Makefile.in (MKDIR_P): New, set by configure.
	* ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.

2012-05-11  Paul Eggert  <eggert@cs.ucla.edu>

	Remove unused function hourglass_started.
	* dispextern.h (hourglass_started):
	* w32fns.c (hourglass_started):
	* xdisp.c (hourglass_started): Remove.

2012-05-10  Juanma Barranquero  <lekktu@gmail.com>

	* makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
	Update dependencies.

2012-05-10  Paul Eggert  <eggert@cs.ucla.edu>

	* xgselect.c (xg_select): Put maxfds+1 into a var.
	This is slightly clearer, and pacifies Ubuntu 12.04 gcc.

	* sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.

2012-05-10  Dave Abrahams  <dave@boostpro.com>

	* filelock.c (syms_of_filelock): New boolean create-lockfiles.
	(lock_file): If create_lockfiles is 0, do nothing.  (Bug#11227)

2012-05-09  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (xd_registered_buses): New internal Lisp object.
	Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
	(syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
	Initialize xd_registered_buses.

2012-05-09  Paul Eggert  <eggert@cs.ucla.edu>

	Untag more efficiently if USE_LSB_TAG.
	This is based on a proposal by YAMAMOTO Mitsuharu in
	<http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
	For an admittedly artificial (nth 8000 longlist) benchmark on
	Fedora 15 x86-64, this yields a 25% CPU speedup.  Also, it shrinks
	Emacs's overall text size by 1%.
	* lisp.h (XUNTAG): New macro.
	(XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
	(XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
	(XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
	* eval.c (Fautoload):
	* font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
	* frame.h (XFRAME): Use XUNTAG.

	Port recent dbusbind.c changes to 32-bit --with-wide-int.
	* dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
	Remove unportable assumptions about print widths of types like
	dbus_uint32_t.
	(xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
	intptr_t when converting between pointer and integer, to avoid GCC
	warnings about wrong width.

2012-05-09  Eli Zaretskii  <eliz@gnu.org>

	* w32proc.c (new_child): Force Windows to reserve only 64KB of
	stack for each reader_thread, instead of defaulting to 8MB
	determined by the linker.  This avoids failures in creating
	subprocesses on Windows 7, see the discussion in this thread:
	http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.

2012-05-07  Jérémy Compostella  <jeremy.compostella@gmail.com>

	Fix up display of the *Minibuf-0* buffer in the mini window.
	* keyboard.c (read_char): Don't clear the echo area if there's no
	message to clear.
	* xdisp.c (redisplay_internal): Redisplay the mini window (with the
	contents of *Minibuf-0*) if there's no message displayed in its stead.

2012-05-07  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
	batch mode.

2012-05-06  Chong Yidong  <cyd@gnu.org>

	* lisp.mk (lisp): Update.

2012-05-05  Jim Meyering  <meyering@redhat.com>

	* w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).

2012-05-04  Stefan Monnier  <monnier@iro.umontreal.ca>

	* data.c (PUT_ERROR): New macro.
	(syms_of_data): Use it.  Add new error type `user-error'.
	* undo.c (user_error): New function.
	(Fprimitive_undo): Use it.
	* print.c (print_error_message): Adjust print style for `user-error'.
	* keyboard.c (user_error): New function.
	(Fexit_recursive_edit, Fabort_recursive_edit): Use it.

2012-05-03  Paul Eggert  <eggert@cs.ucla.edu>

	Do not limit current-time-string to years 1000..9999.
	* editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
	(Fcurrent_time_string): Support any year that is supported by the
	underlying localtime representation.  Don't use asctime, as it
	has undefined behavior for years outside the range -999..9999.

2012-05-02  Paul Eggert  <eggert@cs.ucla.edu>

	Fix race conditions involving setenv, gmtime, localtime, asctime.
	Without this fix, interrupts could mess up code that uses these
	nonreentrant functions, since setting TZ invalidates existing
	tm_zone or tzname values, and since most of these functions return
	pointers to static storage.
	* editfns.c (format_time_string, Fdecode_time, Fencode_time)
	(Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
	Grow the critical sections to include not just invoking
	localtime/gmtime, but also accessing these functions' results
	including their tm_zone values if any, and any related TZ setting.
	(format_time_string): Last arg is now struct tm *, not struct tm **,
	so that the struct tm is saved in the critical section.
	All callers changed.  Simplify allocation of initial buffer, partly
	motivated by the fact that memory allocation needs to be outside
	the critical section.

2012-05-02  Dmitry Antipov  <dmantipov@yandex.ru>

	* intervals.c (adjust_intervals_for_insertion): Initialize `newi'
	with RESET_INTERVAL.

	* buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
	Remove duplicated buffer name initialization.

2012-05-02  Jim Meyering  <jim@meyering.net>

	* xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).

	* xfns.c (x_window): Use xstrdup (Bug#11375).

2012-05-02  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (pos_visible_p): If already at a newline from the
	display string before the 'while' loop, don't walk back the glyphs
	from it3.glyph_row.  Solves assertion violation when the display
	string begins with a newline (egg.el).  (Bug#11367)

2012-05-01  Stefan Monnier  <monnier@iro.umontreal.ca>

	* keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
	Move to simple.el.

2012-05-01  Glenn Morris  <rgm@gnu.org>

	* syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
	s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
	and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
	All were removed before 23.1.

	* dispnew.c: Remove HAVE_LIBNCURSES test;
	it is always true on relevant platforms.

	* Makefile.in (LD_SWITCH_X_SITE_RPATH):
	Rename from LD_SWITCH_X_SITE_AUX_RPATH.

	* Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

2012-04-30  Andreas Schwab  <schwab@linux-m68k.org>

	* .gdbinit (xpr): Remove checks for no longer existing misc types.
	(xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
	Remove.

2012-04-28  Paul Eggert  <eggert@cs.ucla.edu>

	Do not avoid creating empty evaporating overlays (Bug#9642).
	* buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
	That is, do not delete an evaporating overlay if it becomes
	empty after its bounds are adjusted to fit within its buffer.
	This fix caused other problems, and I'm reverting it until we get
	to the bottom of them.

2012-04-27  Chong Yidong  <cyd@gnu.org>

	* xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).

2012-04-27  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (pos_visible_p): If the window start position is beyond
	ZV, start the display from buffer beginning.  Prevents assertion
	violation in init_iterator when the minibuffer window is scrolled
	via the scroll bar.

	* window.c (window_scroll_pixel_based): Likewise.

2012-04-27  Chong Yidong  <cyd@gnu.org>

	* keymap.c (where_is_internal): Doc fix (Bug#10872).

2012-04-27  Glenn Morris  <rgm@gnu.org>

	* fileio.c (Fcopy_file, Fset_file_selinux_context):
	Ignore ENOTSUP failures from setfilecon functions.  (Bug#11245)

2012-04-27  Eli Zaretskii  <eliz@gnu.org>

	* dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
	Don't overrun array limits of glyph row's used[] array.  (Bug#11288)

2012-04-26  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
	display element, check also the underlying string or buffer
	character.  (Bug#11341)

	* w32menu.c: Include w32heap.h.
	(add_menu_item): If the call to AppendMenuW (via
	unicode_append_menu) fails, disable Unicode menus only if we are
	running on Windows 9X/Me.

2012-04-24  Andreas Schwab  <schwab@linux-m68k.org>

	* .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
	(xgetint): Add missing shift for LSB tags.

2012-04-24  Martin Rudalics  <rudalics@gmx.at>

	* keyboard.c (read_char): Don't wipe echo area for select window
	events: These might get delayed via `mouse-autoselect-window'
	(Bug#11304).

2012-04-24  Juanma Barranquero  <lekktu@gmail.com>

	* gnutls.c (init_gnutls_functions): Protect against (unlikely)
	manipulation of :loaded-from data.

2012-04-23  Juanma Barranquero  <lekktu@gmail.com>

	* gnutls.c (init_gnutls_functions): The value of :loaded-from is
	now a cons (bug#11311).

2012-04-23  Paul Eggert  <eggert@cs.ucla.edu>

	Do not create empty overlays with the evaporate property (Bug#9642).
	* buffer.c (Fmove_overlay): Delete an evaporating overlay
	if it becomes empty after its bounds are adjusted to fit within
	its buffer.  Without this fix, in a nonempty buffer (let ((o
	(make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
	yields an empty overlay that has the evaporate property, which is
	not supposed to happen.

	Fix minor GTK3 problems found by static checking.
	* emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
	(EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
	(struct _EmacsFixedClass, emacs_fixed_get_type):
	Move decls here from emacsgtkfixed.h, since they needn't be public.
	(emacs_fixed_get_type): Now static.
	(emacs_fixed_class_init): Omit unused local.
	(emacs_fixed_child_type): Remove; unused.
	* emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
	(EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
	(struct _EmacsFixedClass): Move to emacsgtkfixed.c.
	(EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
	(EMACS_FIXED_GET_CLASS): Remove; unused.
	* gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.

	* keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
	Problem reported by Juanma Barranquero for Windows -Wunused-function.

2012-04-22  Paul Eggert  <eggert@cs.ucla.edu>

	Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
	* gmalloc.c: (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
	(__malloc_size_t, __malloc_ptrdiff_t):
	Remove.  All uses removed, replaced by the definiens if needed,
	since we can assume C89 or better now.
	Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
	(protect_malloc_state, align, get_contiguous_space)
	(malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
	(malloc_atfork_handler_child, malloc_enable_thread)
	(malloc_initialize_1, __malloc_initialize, morecore_nolock)
	(_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
	(_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
	(special_realloc, _realloc_internal_nolock, _realloc_internal)
	(realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
	(freehook, mallochook, reallochook, mabort, mcheck, mprobe):
	Define using prototypes, not old style.
	(align, _malloc_internal_nolock, _free_internal_nolock, memalign):
	Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
	(align): Don't assume that signed integer overflow wraps around.
	Omit unused local var.
	(malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
	(_free_internal_nolock, memalign, mallochook, reallochook):
	Omit no-longer-needed casts.
	(valloc): Use getpagesize, not __getpagesize.
	(MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
	(struct hdr): The 'magic' member is now size_t, not unsigned long.

	* dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.

2012-04-22  Michael Albinus  <michael.albinus@gmx.de>

	Move functions from C to Lisp.  Make non-blocking method calls
	the default.  Implement further D-Bus standard interfaces.

	Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
	* alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
	Do not assume ptrdiff_t is the same width as 'int'.

	* alloc.c: Handle unusual debugging option combinations.
	(GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
	since the two debugging options are incompatible.
	(GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

2012-04-21  Eduard Wiebe  <usenet@pusto.de>

	* sysdep.c (list_system_processes, system_process_attributes):
	Add implementation for FreeBSD (Bug#5243).

2012-04-21  Andreas Schwab  <schwab@linux-m68k.org>

	* print.c (print_preprocess): Only check print_depth if print-circle
	is nil.
	(print_object): Check for cycles even when print-circle is nil and
	print-gensym is t, but only check print_depth if print-circle is nil.

2012-04-20  Chong Yidong  <cyd@gnu.org>

	* process.c (wait_reading_process_output): If EIO occurs on a pty,
	set the status to "failed" and ensure that sentinel is run.

	row, return zero immediately.
	(try_cursor_movement): If inside continuation line, don't back up
	farther than the first row after the header line, if any.
	Don't consider the header-line row as "partially visible", even if
	MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero.  (Bug#11261)

2012-04-20  Atsuo Ohki  <ohki@gssm.otsuka.tsukuba.ac.jp>  (tiny change)

	* lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

2012-04-14  Paul Eggert  <eggert@cs.ucla.edu>

	Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
	* lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
	* s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:

	* s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
	Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
	no longer the default.
	* s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.

2012-04-14  Atsuo Ohki  <ohki@gssm.otsuka.tsukuba.ac.jp>  (tiny change)

	* lread.c (lisp_file_lexically_bound_p):

	* indent.c (Fmove_to_column): Change interactive spec (Bug#739).

2012-04-11  Daniel Colascione  <dancol@dancol.org>

	* s/cygwin.h: The vfork the #define in cygwin.h was protecting
	against is gone.  It's better to use vfork now so that when Cygwin
	gains a new, working vfork, we use it automatically (bug#10398).

2012-04-11  Stefan Monnier  <monnier@iro.umontreal.ca>

	* window.c (save_window_save): Obey window-point-insertion-type.

	not just in the obarray, before snarfing them.  (Bug#11036)

	* Makefile.in ($(leimdir)/leim-list.el):
	Pass EMACS rather than BUILT_EMACS.

2012-04-09  Teodor Zlatanov  <tzz@lifelogs.com>

	* minibuf.c (Fread_variable): Callers changed.

2012-04-09  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (set_cursor_from_row): If the display string appears in
	the buffer at position that is closer to point than the position
	after the display string, display the cursor on the first glyph of
	the display string.  Fixes cursor display when a 'display' text
	property immediately follows invisible text.  (Bug#11094)

2012-04-09  Paul Eggert  <eggert@cs.ucla.edu>

	composite.c: use 'double' consistently
	* composite.c (get_composition_id): Use 'double' consistently
	instead of converting 'float' to 'double' and vice versa; this is
	easier to understand and avoids a GCC warning.

2012-04-09  Glenn Morris  <rgm@gnu.org>

	* Makefile.in: Generate leim-list with bootstrap-emacs, in
	preparation for dumping it with emacs.  (Bug#4789)

2012-04-07  Paul Eggert  <eggert@cs.ucla.edu>

	Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
	* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
	(mark_memory): Mark Lisp_Objects only if pointers might hide in
	objects, as mark_maybe_pointer will catch them otherwise.
	(GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
	* s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

2012-04-07  Paul Eggert  <eggert@cs.ucla.edu>

	Fix typo that broke non-Windows builds.
	* xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

	[!WINDOWSNT]: New macros.
	(init_libxml2_functions, libxml2_loaded_p): New functions.
	(parse_region): Call fn_xmlCheckVersion instead of using the macro
	LIBXML_TEST_VERSION.  Call libxml2 functions via the fn_* macros.
	(xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
	Calls xmlCleanupParser only if libxml2 was loaded (or statically
	linked in).
	(Flibxml_parse_html_region, Flibxml_parse_xml_region):
	Call init_libxml2_functions before calling libxml2 functions.
	(syms_of_xml) <Qlibxml2_dll>: DEFSYM it.

	* emacs.c: Don't include libxml/parser.h.
	(shut_down_emacs): Call xml_cleanup_parser, instead of calling
	xmlCleanupParser directly.

	* lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.

2012-04-07  Eli Zaretskii  <eliz@gnu.org>

	* indent.c (Fvertical_motion): If there is a display string at
	point, use it.vpos to compute how many lines to backtrack after

2012-04-06  Eli Zaretskii  <eliz@gnu.org>

	* buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
	* character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
	about subtle differences between FETCH_CHAR* and STRING_CHAR*

	* w32menu.c (is_simple_dialog): Properly check lisp types.
	(Bug#11141)

2012-03-31  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (move_it_by_lines): When DVPOS is positive, and the
	position we get to after a call to move_it_to fails the
	IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
	only if we wind up in a string from display property.  (Bug#11063)

	* window.c (Fdelete_other_windows_internal): Invalidate the row
	and column information about mouse highlight, so that redisplay
	restores it after reallocating the glyph matrices.  (Bug#7464)

	* xdisp.c (set_cursor_from_row): If `cursor' property on a display
	string comes from a `display' text property, use the buffer
	position of that property as if we actually saw that position in
	the row's glyphs.
	(move_it_by_lines): Remove the assertion that
	"it->current_x == 0 && it->hpos == 0" which can be legitimately
	violated when there's a before-string at the beginning of a line.
	(Bug#11063)

2012-03-30  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (append_space_for_newline): If the default face was
	remapped, use the remapped face for the appended newline.
	(extend_face_to_end_of_line): Use the remapped default face for
	extending the face to the end of the line.
	(display_line): Call extend_face_to_end_of_line when the default
	face was remapped.  (Bug#11068)

2012-03-29  Eli Zaretskii  <eliz@gnu.org>

	* s/ms-w32.h: Discourage from defining HAVE_GETCWD.

2012-03-28  Stefan Monnier  <monnier@iro.umontreal.ca>

	* keyboard.c (safe_run_hooks_error): Don't unquote strings.

2012-03-27  Glenn Morris  <rgm@gnu.org>

	* search.c (Fword_search_backward_lax, Fword_search_forward_lax):
	Doc fixes.

2012-03-26  Kenichi Handa  <handa@m17n.org>

	* dispextern.h (struct glyph): Fix previous change.  Change the

2012-03-25  Fabrice Popineau  <fabrice.popineau@supelec.fr>

	* w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.

2012-03-25  Kenichi Handa  <handa@m17n.org>

	* dispextern.h (struct glyph): Change the bit length of

2012-03-24  Eli Zaretskii  <eliz@gnu.org>

	* s/ms-w32.h (tzname): Include time.h before redirecting to
	_tzname.  Fixes the MSVC build.  (Bug#9960)

	* xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
	characters.

	* xterm.c (XTread_socket): Only modify handling_signal if
	!SYNC_INPUT.  (Bug#11080)

2012-03-23  Eli Zaretskii  <eliz@gnu.org>

	* bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
	FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES.  Prevents crashes
	when fetching a multibyte character consumes more bytes than
	CHAR_BYTES returns, due to unification of CJK characters in
	string_char.  (Bug#11073)

2012-03-23  Troels Nielsen  <bn.troels@gmail.com>  (tiny change)

	* process.c (wait_reading_process_output): Handle pty disconnect

	(Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
	Doc fixes.

2012-03-20  Chong Yidong  <cyd@gnu.org>

	* dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc

	that is not from display property, accept the row as a "cursor
	row" if one of the string's character has a non-nil `cursor'
	property.  Fixes cursor positioning when there are newlines in
	overlay strings, e.g. in icomplete.el.  (Bug#11035)

2012-03-12  Paul Eggert  <eggert@cs.ucla.edu>

	* buffer.c (buffer-list-update-hook): Doc fix.

2012-02-29  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
	push_it before setting up the iterator for the first overlay
	string, even if we have an empty string loaded.
	(next_overlay_string): If there's an empty string on the iterator
	stack, pop the stack.  (Bug#10903)

2012-02-25  Paul Eggert  <eggert@cs.ucla.edu>

	Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
	Suggested by Stefan Monnier in
	<http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
	* alloc.c (widen_to_Lisp_Object): New static function.
	(mark_memory): Also mark Lisp_Objects by fetching pointer words
	and widening them to Lisp_Objects.  This would work even if
	USE_LSB_TAG is defined and wide integers are used, which might
	happen in a future version of Emacs.

2012-02-25  Chong Yidong  <cyd@gnu.org>

	* fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
	Doc fix.

	requests in kbd_buffer, not just the next one (Bug#8869).

2012-02-23  Chong Yidong  <cyd@gnu.org>

	* xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
	call when setting menu-bar-lines and tool-bar-lines parameters.
	(unwind_create_frame_1): New helper function.

	* window.c (inhibit_window_configuration_change_hook): New var.

	when computing $valmask.

	Fix crash due to non-contiguous EMACS_INT (Bug#10780).
	* lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
	(USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
	It's useless in that case, and it can cause problems on hosts
	that allocate halves of EMACS_INT values separately.
	Reported by Dan Horák.  Diagnosed by Andreas Schwab in
	<http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
	* mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
	UINTPTR_MAX >> VALBITS == 0.  This is required by the above change;
	it avoids undefined behavior on hosts where shifting right by more
	than the word width has undefined behavior.

2012-02-19  Chong Yidong  <cyd@gnu.org>

	* fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
	(Funhandled_file_name_directory, Ffile_name_as_directory)
	(Fdirectory_file_name, Fexpand_file_name)
	(Fsubstitute_in_file_name): Protect against invalid file handler
	return values (Bug#10845).

2012-02-18  Eli Zaretskii  <eliz@gnu.org>

2012-02-15  Chong Yidong  <cyd@gnu.org>

	* eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
	marked as special.  Also, starting docstrings with * is obsolete.

2012-02-13  Andreas Schwab  <schwab@linux-m68k.org>
