Quote less in manuals

The manuals often used quotes ``...'' when it is better to use @dfn or
@code or capitalized words or no quoting at all.  For example, there is
no need for the `` and '' in “if a variable has one effect for
@code{nil} values and another effect for ``non-@code{nil}'' values”.
Reword the Emacs, Lisp intro, and Lisp reference manuals to eliminate
unnecessary quoting like this, and to use @dfn etc. instead when called
for (Bug#21472).

Add separator.pbm tool-bar image

* etc/images/separator.pbm: New file.  Having it avoids the side
effect of changing the tool-bar height when the default font's size
changes and XPM image support is not available, due to the SPC
characters that are left in the Lisp string used to display the tool
bar, because there are no images to display instead of those SPC
characters.

Make show-paren-match face visible on mono-color displays

`cadr/car'.

slot numbers are zero-based.  (Bug#21467)

* src/indent.c (Fvertical_motion): Don't leave point in the middle

; Fix stray quote inserted in comment

Improvements for curved quotes on Linux consule

This should help Emacs work better out-of-the-box on Linux consoles,
which have only limited support for displaying Unicode characters.
Also, undo the recent change that caused text-quoting-style to
affect quote display on terminals, so that the two features are
independent.  See Alan Mackenzie in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00244.html
Finally, add a style parameter to startup--setup-quote-display,
so that this function can also be invoked after startup, with
different styles depending on user preference at the time.
* configure.ac: Check for linux/kd.h header.
* doc/emacs/display.texi (Text Display): Document quote display.

* lisp/international/mule-util.el (char-displayable-p):
* lisp/startup.el (startup--setup-quote-display):
On a text terminal supporting glyph codes, use the reported
glyph codes instead of the terminal coding system, as this
is more accurate on the Linux console.
* lisp/startup.el (startup--setup-quote-display):
New optional arg STYLE.
* src/fontset.c (Finternal_char_font):
Report glyph codes for a text terminal, if they are available.
Currently this is supported only for the Linux console.
* src/termhooks.h (struct terminal): New member glyph-code-table.
* src/terminal.c [HAVE_LINUX_KD_H]: Include <errno.h>, <linux/kd.h>.

(tetris-mode-map): Use it.

Copyright-paperwork-exempt: yes

; Fix comment to match recent code change

Remove a few simple cases of global redisplay

* src/dispnew.c (redraw_frame): Don't redisplay all frames.

* src/xdisp.c (echo_area_display): Set the frame's `redisplay' bit
rather than returning a "resized_p" boolean.
(redisplay_internal): Adjust call accordingly.

* src/xfaces.c (free_realized_faces): Don't redisplay all frames.
(free_all_realized_faces): Set windows_or_buffers_changed so as to ease
tracking of this undesirable situation.

* src/process.c (status_notify): Avoid global redisplay (bug#11822)

* src/process.c (status_notify): Only set the update_mode_line on the
relevant buffers rather than setting it globally.

; Auto-commit of loaddefs files.

(electric-quote-mode): Activate everywhere in message-mode

* lisp/electric.el (electric-quote-post-self-insert-function):
Don't use syntax-ppss if comment-use-syntax is nil (e.g. message-mode).

Go back to grave quoting in source-code docstrings etc.

This reverts almost all my recent changes to use curved quotes
in docstrings and/or strings used for error diagnostics.

configuration to `package--activate-autoloads-and-load-path'.

; Add (tiny change) an entry from 2015-08-31

* src/keyboard.c (read_key_sequence): Complete last fix (bug#21403)

Fix deletion of symlinks to directories on MS-Windows

* src/w32.c (sys_unlink): If 'unlink' fails, and the argument is a
symlink to a directory, try again with 'rmdir'.
(is_symlink): If the argument is a symlink to a directory, set a
bit in the return value to indicate that fact.

* lisp/emacs-lisp/package.el (package-initialize): Set enable-at-startup

When `package-initialize' is called as part of loading the init file,
the user probably doesn't want it to be called again afterwards. In this
situation, `package-initialize' now sets `package-enable-at-startup' to
nil to prevent that. The user can have the old behaviour by setting this
variable to t after the call to `package-initialize'.  (Bug#21423)

check for that.

* lisp/filenotify.el (file-notify-handle-event):
(file-notify--pending-event): Adapt docstring.

order to support renaming over directory boundaries.
