Apple changed the spelling of its operating system again, to "macOS",
effective with macOS 10.12 Sierra (2016-09-20). Change Emacs
documentation and comments to match this. Stick with older OS
spellings ("OS X", "Mac OS X") when talking about older releases where
the older names are more correct.
* lisp/international/characters.el (char-width-table): Add missing
range U+1F400..U+1F43E. (Bug#24699)
* admin/notes/unicode: Mention the need to verify char-width-table
setting against data in EastAsianWidth.txt.
* gitmerge.el (gitmerge-skip-regexp): Add "cherry picked from commit",
which is the string appended by 'git cherry-pick -x'.
(cherry picked from commit f648e48669)
* doc/lispref/abbrevs.texi (Abbrev Files, Abbrev Expansion):
* doc/emacs/abbrevs.texi (Dabbrev Customization): State the
default values of variables. Suggested by Steve Byrne
<sbb@penguinis.org>. (Bug#23016)
* admin/release-process (Check manuals): Mark files reviewed by
Steve Byrne.
* admin/unidata/UnicodeData.txt:
* admin/unidata/Blocks.txt:
* admin/unidata/BidiMirroring.txt:
* admin/unidata/BidiBrackets.txt: Update from Unicode 9.0.0beta.
* admin/unidata/unidata-gen.el (unidata-gen-files): Bind
'coding-system-for-read' to 'utf-8, as various Unicode data files
now actually use non-ASCII characters.
(unidata-setup-list, unidata-get-name): Support the new Tangut
Ideographs block.
* lisp/international/characters.el (standard-case-table): Add new
characters from Unicode 9.0.0.
(standard-category-table): Add Arabic block u+08A0..u+08FF. Add
Cyrillic Extended-C block.
(char-width-table): Update ranges per Unicode 9.0.0.
* lisp/international/fontset.el (script-representative-chars): Add
new scripts defined by Unicode 9.0.0.
(otf-script-alist): Add new OTF script tags.
* lisp/international/mule-cmds.el (ucs-names): Update ranges per
Unicode 9.0.0 additions.
* admin/notes/unicode: Update the list of files from the UCD we
are using. Mention the possible need to change 'ucs-names' when
importing a new version of the Unicode Standard.
Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
* CONTRIBUTE: Mention URLs and info nodes more consistently,
avoiding possibly-confusing punctuation adjacent to a URL, and
giving full shell commands for 'info'. Start with a brief but
complete how-to, for people who want to get started right away.
Then briefly discuss how to join the development process in the
typical order. Omit needless words. Update some of the
now-obsolete file names, info node names, and quoting styles.
Better document emacs-NN branches and how they are merged.
* admin/notes/git-workflow: Change emacs-24 to emacs-25,
and trunk to master. This file still needs work.

Pavel Raiskup reports that ${1+"$@"} runs afoul of a bug in /bin/sh
(derived from ksh 93t+ 2010-03-05). ${1+"$@"} works around an ancient
bug in long-dead shells, so remove the workaround.
* admin/check-doc-strings, configure.ac, lib-src/rcs2log:
Use plain "$@" rather than ${1+"$@"}.
* admin/merge-gnulib (GNULIB_MODULES): Add ignore-value.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/ignore-value.h: New file, from gnulib.
* src/keyboard.c: Include it.
(write_stdout, read_stdin): New functions.
(handle_interrupt): Use them instead of printf and getchar,
and avoid fflush when handling signals.
