Plus miscellaneous minor speling fixes in other manual files.
* doc/emacs/files.texi (File Names, Visiting, Interlocking): Copyedits.
(Backup Copying): backup-by-copying-when-mismatch is now t.
(Customize Save): Fix description of require-final-newline.
(Reverting): Note that revert-buffer can't be undone. Mention VC.
(Auto Save Control): Clarify.
(File Archives): Add 7z.
(Remote Files): ange-ftp-make-backup-files defaults to nil.
* doc/emacs/arevert-xtra.texi (Autorevert): Copyedits.
src/dispextern.h (struct bidi_it): New member next_en_type.
src/bidi.c (bidi_line_init): Initialize the next_en_type member.
(bidi_resolve_explicit_1): When next_en_pos is valid for the
current character, check also for next_en_type being WEAK_EN.
(bidi_resolve_weak): Don't enter the expensive loop if the current
position is before next_en_pos. Record the bidi type of the first
non-ET, non-BN character we find, in addition to its position.
(bidi_level_of_next_char): Invalidate next_en_type when
next_en_pos is over-stepped.
* configure.in (AC_STRUCT_TM, AC_STRUCT_TIMEZONE, HAVE_TM_GMTOFF):
Remove; no longer needed, now that we defer to strftime for time
zone names.
* src/editfns.c: Rewrite current-time-zone so that it invokes
the equivalent of (format-time-string "%Z") to get the time zone name.
This fixes a bug when the time zone name contains characters that
need converting from the system time locale to Emacs internal format.
This fixes a shortcoming that I introduced in my 1999-10-19 patch:
that patch fixed format-time-string to do the conversion, but
I forgot to fix current-time-zone.
(format_time_string): New function, containing most of
what Fformat_time_string used to contain.
(Fformat_time_string): Rewrite in terms of format_time_string.
This doesn't change this function's behavior.
(current-time-zone): Rewrite to use format_time_string.
This fixes the bug reported by Michael Schierl in
<http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
Jason Rumney's 2007-06-07 change worked around this bug, but
didn't fix it.
* src/systime.h (tzname, timezone): Remove no-longer-used declarations.
* doc/emacs/custom.texi (Hooks, Init Examples):
* doc/emacs/display.texi (Font Lock):
* doc/emacs/fixit.texi (Spelling):
* doc/emacs/rmail.texi (Rmail Display): Minor mode function with no arg now
enables it.
* doc/emacs/fixit.texi (Spelling): Fix description of inline completion.
src/xdisp.c (try_window_reusing_current_matrix): If a line ends in a display
vector or the next line starts in a display vector, continue
redrawing the window even though the character position of
start_row was reached.
Fixes: debbugs:9771
(browse-url-chromium-program, browse-url-chromium-arguments):
New defcustoms.
(browse-url-default-browser): Check for `browse-url-chromium' and
call `browse-url-chromium-program'.
(browse-url-chromium): New command.
Fixes: debbugs:9779
* doc/emacs/display.texi (Fringes): Move overflow-newline-into-fringe here,
from Line Truncation node.
(Standard Faces): Note that only the background of the cursor face
has an effect.
(Cursor Display): Fix descriptions of cursor face
and bar cursor blinking.
(Text Display): Document nobreak-char-display more clearly.
(Line Truncation): Add xref to Split Window node.
(Display Custom): Don't bother documenting baud-rate or
no-redraw-on-reenter.
* doc/emacs/search.texi (Slow Isearch): Node removed.
src/bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
(bidi_resolve_neutral): Don't enter the expensive loop looking for
non-neutral characters if the current character is a paragraph
separator (a.k.a. Newline). This avoids running the same
expensive loop twice, once when we consume the preceding newline
and the other time when the line actually needs to be displayed.
Avoid the loop when we see neutrals on the base embedding level
following a character whose directionality is the same as the
paragraph's. This avoids running the expensive loop when a line
ends in a long sequence of neutrals, like control characters.
Add assertion against STRONG_AL type. Slightly rearrange code
that determines the type of a neutral given the first non-neutral
that follows it.
(bidi_level_of_next_char): Set next_en_pos to zero when
invalidating its info.
gnus-util.el (gnus-bound-and-true-p): Macro for XEmacs compatibility.
nnir.el (nnir-mode): Use it.
nnmairix.el (nnmairix-determine-original-group-from-registry): Use it.
nnir.el (gnus-registry-enabled): Defvar to keep the compiler happy.
nnmairix.el (gnus-registry-enabled): Ditto.
Add support for detecting encoding in HTML5 specified only as
<meta charset="UTF-8">. Implementation just makes http-equiv and
content-type parts from HTML4 encoding string optional.
Fixes: debbugs:9716
* doc/emacs/display.texi (Faces): Simplify discussion. Move documentation
of list-faces-display here, from Standard Faces node. Note
special role of `default' background.
(Standard Faces): Note special role of `default' background. Note
that region face may be taken fom GTK. Add xref to Text Display.
(Text Scale): Rename from "Temporary Face Changes". Callers
changed. Don't bother documenting variable-pitch-mode.
(Font Lock): Copyedits. Remove font-lock-maximum-size.
(Useless Whitespace): Simplify description of
delete-trailing-whitespace. Note active region case.
(Text Display): Fix description of escape-glyph face assignment.
Remove unibye mode discussion. Update some parts for Unicode.
Move glyphless chars documentation to Lisp manual.
* doc/emacs/frames.texi (Tooltips): Document x-gtk-use-system-tooltips.
* doc/lispref/display.texi (Glyphless Chars): New node.
