* src/xdisp.c (redisplay_internal): Inhibit freeing of realized
faces for as long as we might have desired matrices that reference
those faces. (Bug#21428)
1. Allow point to move between follow windows in scroll operations.
2. Fix bug where `right-char' just before EOB caused spurious scrolling,
when EOB was isolated in the last follow window.
lisp/follow.el (follow-fixed-window): New variable.
(follow-get-scrolled-point): New function.
(follow-scrol-up, follow-scroll-down): Add autoload cookies.
Reformulate
the code. Put `scroll-command' properties on the functions. Correct
minor errors in ...-down's doc string and code.
(follow-calc-win-end): Amend incomplete doc string. Use
`pos-visible-in-window-p' to check whether EOB is in the window.
(follow-estimate-first-window-start): Correct an off-by-1 error.
(follow-adjust-window): Add handling for explicit scrolling operations.
* src/frame.h (struct f): New flag face_change.
* src/xfaces.c (Finternal_make_lisp_face)
(Finternal_copy_lisp_face, Finternal_set_lisp_face_attribute)
(update_face_from_frame_parameter): Set the face_change flag only
for the frame whose faces are affected.
* src/xdisp.c (init_iterator): If a frame's face_change flag is
set, free faces only on that frame.
(redisplay_internal): Disable "display optimization 1" if the
frame's face_change flag is set.
(redisplay_window): Don't allow skipping a window's redisplay if
its frame's face_change flag is set.
* src/frame.c (x_set_screen_gamma): Instead of calling
Fclear_face_cache, call clear_face_cache and set
windows_or_buffers_changed to a non-zero value. This avoids
setting the global face_change flag that triggers face realization
on all frames and thorough redisplay of all of them.
* lisp/term/tty-colors.el (tty-register-default-colors): Don't
clear face cache if the selected frame is a GUI frame.
* src/nsterm.m:
* src/lisp.h:
* src/editfns.c:
* src/doprnt.c: Add 'coding' cookies -- these files include
Unicode characters and should be decoded as UTF-8.
lisp/emacs-lisp/edebug.el (edebug-initial-mode-alist): Uncomment, and
amend to match current modes and functions.
(edebug-set-initial-mode): Uncomment and change from setting a defun's
`edebug-initial-mode''s property to setting the variable
`edebug-initial-mode'.
(top level): Create new binding C-x C-a C-m for
`edebug-set-initial-mode'.
doc/lispref/edebug.texi (Edebug Execution Modes): document
`edebug-set-initial-mode' and its new key binding.
(Edebug Options): Mention the new command in the pertinent place.
etc/NEWS: Write entry for this change.

2015-09-25 c-ctype: rewrite to use inline functions
2015-09-24 maint: add coding cookies to non-ASCII sources
2015-09-24 gitlog-to-changelog: trim only trailing whitespaces

* src/xdisp.c (produce_stretch_glyph): Support ':relative-width'
space display spec on text-mode terminals, by calling
PRODUCE_GLYPHS instead of x_produce_glyphs. Remove the HAVE_WINDOW_SYSTEM
guards from the supporting code, as well as the test for a GUI frame.
