* lisp/progmodes/grep.el (rgrep-default-command): Remove nil from
the list produced according to grep-find-ignored-directories,
before passing it to Find/Grep invocation. (Bug#21548)
* src/window.c (Fpos_visible_in_window_p): Clarify the meaning of
t for POS. See
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg01040.html
for the original report.
* doc/lispref/windows.texi (Window Start and End): Clarify the
meaning of t for the POSITION argument of pos-visible-in-window-p.
(prolog-operator-chars): New const (add \\).
(prolog-smie-forward-token, prolog-smie-backward-token): Use it.
(prolog-smie-rules): Add rules according to bug#21526.
(sh-indent-after-continuation): Add new value `always' (bug#17620)
(sh-smie-sh-rules): Remove old handling of continued lines.
(sh-smie--indent-continuation): New function.
(sh-set-shell): Use it.
Remove redundant :group keyword args.
(octave-begin-keywords, octave-else-keywords, octave-end-keywords):
Remove variables.
(octave-operator-table, octave-smie-bnf-table): Use let-when-compile to
turn them into compile-time variables.
Auto-generate the "foo ... end" rules from the "foo ... endfoo" rules.
Add rules for break, continue, return, global, and persistent.
Refine the rule for "until".
(octave-smie--funcall-p, octave-smie--end-index-p)
(octave-smie--in-parens-p): New functions.
(octave-smie-backward-token, octave-smie-forward-token): Use them to
distinguish the "enumeration" function and the "end" index from
their corresponding keywords.
(octave--block-offset-keywords): New constant.
(octave-smie-rules): Use it. Adjust rules for new global/persistent parsing.
(octave-reserved-words): Redefine using octave-smie-grammar.
(octave-font-lock-keywords): Use octave-smie--funcall-p and
octave-smie--end-index-p.
* doc/lispref/sequences.texi: Add documentation regarding extending
seq.el, as well as missing documentation for seq-elt, seq-length, seq-p,
seq-do and seq-map.
* doc/lispref/sequences.texi:
* lisp/emacs-lisp/seq.el: Update the documentation of seq-some to
guarantee that the returned value is the first non-nil value that
resulted from applying the predicate.
* 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.
