See discussion at http://lists.gnu.org/archive/html/emacs-devel/2011-10/msg00193.html
* lisp/simple.el (count-words-region): Always count in the region.
Report the number of lines and characters too.
(count-words): New command, which counts in the buffer if the
region is inactive, as count-words-region used to.
(count-words--message): New function. Handle plurals.
(count-lines-region): Make it an alias for count-words-region.
* lisp/bindings.el (esc-map): Replace count-lines-region with
count-words-region.
* doc/emacs/basic.texi (Position Info): Omit page commands. Document
count-words-region and count-words.
* doc/emacs/text.texi (Pages): Move what-page documentation here.
* doc/emacs/mini.texi (Minibuffer File): Minor copyedits. Use xref to
Remote Files node instead of linking directly to the Tramp manual.
(Minibuffer Edit): Add xref to Blank Lines.
(Completion): Add xref to Symbol Completion. Remove redundant
example, which is repeated in the next node.
(Completion Commands): Minor clarifications.
(Completion Styles): New node, split from Completion Commands.
Document substring and initials styles.
(Strict Completion): Remove information duplicated in other nodes.
(Completion Options): Consolidate case difference discussion here.
* doc/emacs/files.texi (File Names): Add index entries.
* doc/emacs/help.texi (Help Mode): Fix kindex entries.
* lib/signal.in.h, lib/sigprocmask.c, m4/gl-comp.m4:
* m4/gnulib-common.m4: Merge from gnulib.
Without this, 'configure' would say "func_gl_gnulib_m4code_pathmax:
command not found" on powerpc-apple-darwin9.8.0.
* doc/emacs/basic.texi (Inserting Text): Add xref to Completion. Add
ucs-insert example, and document prefix argument.
(Moving Point): Fix introduction; C-f/C-b are no longer equivalent
to left/right. Tweak left-char and right-char descriptions.
M-left and M-right are now bound to left-word/right-word.
(Erasing): Document delete-forward-char.
* doc/emacs/commands.texi (User Input): Define "input event" more clearly.
(Keys): Add xref to Echo Area.
(Commands): Clarify relation between commands and functions.
* doc/emacs/entering.texi (Entering Emacs): Define "startup screen".
Document window-splitting behavior with command-line inputs.
(Exiting): Remove obsolete paragraph about shells without suspend
functionality.
* doc/emacs/frames.texi (Non-Window Terminals): Index just "text-only
terminal", which is used throughout the manual now.
* doc/emacs/screen.texi (Screen, Menu Bar): Copyedits.
(Point): Remove duplicate paragraph on cursors, also in Screen.
(Mode Line): Trailing dashes no longer shown on X displays.
* configure.in (GC_LISP_OBJECT_ALIGNMENT): Remove.
This is now done by src/alloc.c.
* src/alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
this makes Emacs dump core during garbage collection on rare
occasions. sizeof is obviously inferior to offsetof here, so
stick with offsetof.
(GC_POINTER_ALIGNMENT): New macro.
(mark_memory): Omit 3rd (offset) arg; caller changed.
Don't assume EMACS_INT alignment is the same as pointer alignment.
gnus.texi (Gnus Utility Functions): Add more references and explanations (bug#9683).
ecomplete.el (ecomplete-display-matches): Use a local keymap to handle bindings.
gnus-win.el (gnus-configure-windows): Protect against reading ephemeral groups outside of Gnus.
* doc/emacs/misc.texi (emacsclient Options): Document how emacsclient
runs the Emacs daemon.
* doc/man/emacsclient.1: Document how -a "" starts the daemon.
Fixes: debbugs:9674
* window.el (window-point-1, set-window-point-1): New functions.
(window-in-direction, record-window-buffer, window-state-get-1)
(display-buffer-record-window): Use window-point-1 instead of
window-point.
(set-window-buffer-start-and-point): Use set-window-point-1.
* window.el (frame-auto-hide-function): New option replacing
frame-auto-delete. Suggested by Stefan Monnier.
(window--delete): Call frame-auto-hide-function instead of
investigating frame-auto-delete.
