since callers should never pass a negative size.
Change the signature to match that of plain 'read' and 'write'; see
<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
* lisp.h: Update prototypes of emacs_write and emacs_read.

* lisp/calendar/cal-tex.el (cal-tex-end-document):
Try to automatically use latin1 input if needed.

* lisp/calendar/cal-hebrew.el (diary-hebrew-rosh-hodesh):
Don't try to cons a mark onto an empty element.

Recipe showing the problem:
~/diary:
&%%(diary-rosh-hodesh)
&%%(diary-parasha)

emacs -Q --eval "(progn (add-hook 'diary-nongregorian-listing-hook
   'diary-hebrew-list-entries) (setq cal-tex-diary t))" -f calendar

[Port to 23.4]

* configure.in: Require ImageMagick >= 6.2.8.  (Bug#7955)

* etc/NEWS: Mention ImageMagick version.

gnus-registry.el (gnus-registry-action): Remove properties and simplify subject in `gnus-registry-handle-action'.
 (gnus-registry-spool-action): Get subject and sender from message if they are not passed in.
 (gnus-registry-handle-action): Remove properties and simplify subject consistently.

 src/xdisp.c (redisplay_window): Don't try to determine the character
 position of the scroll margin if the window start point w->startp
 is outside the buffer's accessible region.

 src/xdisp.c (redisplay_window): Don't try to determine the character
 position of the scroll margin if the window start point w->startp
 is outside the buffer's accessible region.

* lisp/minibuffer.el (completion-show-inline-help): New var.
(completion--do-completion, minibuffer-complete)
(minibuffer-force-complete, minibuffer-complete-word): Inhibit
minibuffer messages if completion-show-inline-help is nil.

* lisp/icomplete.el (icomplete-mode): Bind completion-show-inline-help
to avoid interference from inline help.

 src/fileio.c (a_write, e_write): Modify declaration of arguments and
 local variables to support buffers larger than 2GB.
 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
 src/sysdep.c (emacs_write, emacs_read): Use ssize_t for last
 argument, local variables, and return value.
 src/lisp.h: Update prototypes of emacs_write and emacs_read.
 src/sound.c (vox_write): Use ssize_t for return value of emacs_write.

* gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
return ssize_t not "int", and use size_t as the buffer length.
(emacs_gnutls_write): Likewise, and make the buffer pointer "const".
* gnutls.h: Update declarations.
* process.c (read_process_output): Use ssize_t, to match.
(send_process): Likewise.

See <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8435#26>.

This also lets GCC 4.6.0 generate slightly better loop code.

* lisp/image-mode.el (image-toggle-display-image): Signal an error if
not in Image mode.
(image-transform-mode, image-transform-resize)
(image-transform-set-rotation): Doc fix.
(image-transform-set-resize): Deleted.
(image-transform-set-scale, image-transform-fit-to-height)
(image-transform-fit-to-width): Handle image-toggle-display-image
and image-transform-resize directly.

* src/image.c (Fimagemagick_types): Doc fix, and comment cleanup.

(Fcall_interactively): Count the number of arguments produced,
not the number of arguments given.  This is simpler and lets GCC
4.6.0 generate slightly better code.

The previous code passed unsigned char * to a functions like
strlen and xstrcasecmp that expect char *, which does not
conform to the C standard.
(get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
arguments to FcPatternGetString, and explicitly cast FcChar8 * to
char * when the C standard requires it.
