(Reading from Files): Copyedits.
(File Attributes): Mention how to change file modes.
(Changing Files): Use standard "file permissions" terminology.
Add xref to File Attributes node.
(Locating Files): Document locate-user-emacs-file.
(Unique File Names): Recommend against using make-temp-name.

* src/buffer.c (Fget_file_buffer): Protect against invalid file
handler return value.

* src/fileio.c (Vfile_name_handler_alist): Doc fix.

* doc/emacs/picture-xtra.texi (Basic Picture): C-a does get remapped.

* lisp/textmodes/picture.el (picture-motion, picture-motion-reverse)
(picture-self-insert, picture-tab-chars): Doc fix.
(picture-mode-map): Fix C-a, C-e.

* admin/FOR-RELEASE: Related markup.

* doc/emacs/ack.texi (Acknowledgments): Small changes, including resorting,
and removal of things no longer distributed.
* admin/FOR-RELEASE: Related markup.

* etc/emacs-buffer.gdb ($valmask): Don't assume EMACS_INT fits in 'long'.
* src/.gdbinit (xreload): Likewise.

* doc/emacs/emacs.texi (Top, Preface): Small rephrasings.
(menu, detailmenu): Update entries, and reformat some descriptions.
* doc/emacs/building.texi, doc/emacs/display.texi:

* admin/FOR-RELEASE: Related markup.

* 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.

* url-queue.el (url-queue-kill-job): Delete the process sentinel
before killing the process to avoid a race condition between the
two processes killing off the process buffer.

nnimap.el (nnimap-request-list): Return the group names encoded as utf8.  Otherwise non-European group names don't work.
 (nnimap-request-newgroups): Ditto.
gnus-sum.el (gnus-summary-insert-old-articles): Fix the syntax for the default in `read-string' (bug#10757).

* url.el (url-retrieve-internal): Warn about file errors when
pruning the cache instead of bugging out.

See: http://debbugs.gnu.org/10850

nnimap.el: IMAP command logging improvement; When moving articles between IMAP servers, delete from the correct server

* ansi-color.el: Don't set comint-output-filter-functions; it is
now in the initial value defined in comint.el.
(ansi-color-apply-face-function): New variable.
(ansi-color-apply-on-region): Use it.
(ansi-color-apply-overlay-face): New function.

* comint.el: Require ansi-color.
(comint-output-filter-functions): Add ansi-color-process-output.

* shell.el (shell): No need to require ansi-color.
(shell-mode): Use ansi-color-apply-face-function to highlight
color escapes using font-lock-face property.

Fixes: debbugs:10835

* src/fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
(Funhandled_file_name_directory, Ffile_name_as_directory)
(Fdirectory_file_name, Fexpand_file_name)
(Fsubstitute_in_file_name): Protect against invalid file
handler return values.

Fixes: debbugs:10845

* url-queue.el (url-queue-callback-function): Remove the job from
the queue so that we don't kill the current buffer, which will
then make the callback function kill a random buffer.

* lisp/vc/ediff-init.el (ediff-strip-mode-line-format): Handle non-list
mode-line formats.

Fixes: debbugs:10839

* doc/lispref/help.texi (Documentation, Documentation Basics, Help Functions):
Minor clarifications.
(Accessing Documentation): Clarify what documentation-property is
for.  Add xref to Keys in Documentation.

* doc/lispref/macros.texi (Defining Macros):
* doc/lispref/modes.texi (Derived Modes): Say "documentation string" instead
of docstring.

* doc/lispref/tips.texi (Documentation Tips): Don't recommend using * in
docstrings.
