src/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.
* src/dispextern.h (struct it): New member string_from_prefix_prop_p.
* src/xdisp.c (push_prefix_prop): Renamed from push_display_prop.
Mark string as coming from a prefix property.
(handle_face_prop): Use default face for prefix strings.
(pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
Fixes: debbugs:4281
* doc/lispref/display.texi (The Echo Area): Add xref to Output Streams.
(Displaying Messages): Improve doc of message.
(Echo Area Customization, Invisible Text): Copyedits.
(Invisible Text): Mention that spec comparison is done with eq.
(Width): Improve doc of char-width.
(Faces): Recommend using symbol instead of string for face name.
Minor clarifications.
(Defining Faces): Copyedits. Update face example.
(Attribute Functions): Mark set-face-foreground etc as commands.
(Face Remapping): Mention text-scale-adjust. Clarify
face-remapping-alist and related docs.
(Face Functions): Don't document make-face or copy-face.
* lisp/faces.el (make-face, make-empty-face, copy-face):
* lisp/face-remap.el (face-remap-add-relative, face-remap-set-base):
Doc fixes.
* src/xfaces.c (Vface_remapping_alist): Doc fix.
* doc/lispref/display.texi (Forcing Redisplay): Various rewrites to reflect
new value of redisplay-dont-pause.
(Truncation): Copyedits.
* src/dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
to reflect default non-nil value of redisplay-dont-pause.
src/xdisp.c (cursor_row_p): Even if the glyph row ends in a string
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.
This is a tweak to 2012-02-23T07:28:21Z!cyd@gnu.org, suggested by Stefan.
* eval.c (inhibit_lisp_code): Rename from
inhibit_window_configuration_change_hook; move from window.c.
* xfns.c (unwind_create_frame_1, Fx_create_frame):
* window.c (run_window_configuration_change_hook)
(syms_of_window): Callers changed.
src/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.

<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.
See thread at http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00573.html
* src/window.c (inhibit_window_configuration_change_hook): New var.
(run_window_configuration_change_hook): Obey it.
* src/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.
* 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.
* lisp/custom.el (defcustom): Doc fix; note use of defvar.
* src/eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
marked as special. Also, starting docstrings with * is obsolete.
