* lisp/vc/vc-git.el (vc-git-register):
Use file names verbatim with 'git update-index', as it only accepts
file names, not pathspecs (bug#39452).
* lisp/vc/vc.el (vc-print-root-log):
Expand ROOTDIR, so that vc-git-print-log doesn't receive an
abbreviated name. Literal pathspecs don't work with those.
This fixes bug #47468.
* lisp/progmodes/cc-engine.el (c-looking-at-inexpr-block): While searching
backwards for "->" which is a type indicating operator, disallow also commas.
Also optimize a loop over several line doc-comments.
* lisp/progmodes/cc-fonts.el (c-font-lock-doc-comments): New variable
comment-mid, used as the starting point for applying c-doc-face-name in a
line comments. In block comments, apply this face not from `comment-beg' but
from `region-beg', no earlier than the start of the fontification region.
Fixes: bug#49888
* minibuffer.el (completion--flex-adjust-metadata): Fall back to usual
alphanumeric, length, recency strategy if no minibuffer input. There
is still a bug indicated by the nearby FIXMEs, though.
* lisp/simple.el (execute-extended-command): Run the key binding
suggestion from a timer instead of in the program flow -- this
allows `post-command-hook' to be executed immediately (bug#50042).
When the same buffer is displayed in more than one window,
redisplay temporarily moves point to the window-point when it
works on non-selected windows. If we allow C-g to quit out of
redisplay_window in this situation, point will appear to have
moved to the window-point of that non-selected window, which is
unwarranted. These changes prevent quitting in strategic places,
so that we never quit out of redisplay_window.
* src/xdisp.c (run_window_scroll_functions):
Prevent quitting while running window-scroll-functions, so that we
don't quit out of redisplay_window with temporarily moved point.
(redisplay_window): While redisplaying the mode line, prevent
quitting, to avoid exiting while point is temporarily moved.
(decode_mode_spec): Use safe_call1 instead of call1, to trap any
errors instead of letting them throw out of redisplay. (Bug#44448)
C-x p p utilizes a completion table "category" which is 'project-file'
icomplete-fido-kill only functioned for 'buffer' and 'file', and
failed with a non-informative message when something else was used.
* lisp/icomplete.el (icomplete-fido-kill): Support 'project-file'
class. Use cl-case, instead of pcase.
* doc/lispref/sequences.texi (seq-setq): Document this macro.
* lisp/emacs-lisp/seq.el (seq-setq): New macro.
* test/lisp/emacs-lisp/seq-tests.el (test-seq-setq):
Test this macro (bug#50053).
* lisp/emacs-lisp/map.el: Bump version to 3.1.
(map--merge): New merging subroutine that uses a hash table in place
of lists, for both efficiency and avoiding ambiguities (bug#49848).
(map-merge): Rewrite in terms of map--merge.
(map-merge-with): Ditto. This ensures that FUNCTION is called
whenever two keys are merged, even if they are not eql (which could
happen until now). It also makes map-merge-with consistent with
map-merge, thus achieving greater overall predictability.
* etc/NEWS: Announce this weakening of guarantees.
* test/lisp/emacs-lisp/map-tests.el (test-map-merge)
(test-map-merge-with): Don't depend on specific orderings. Test
that nil is correctly merged into a plist.
This face is intended for mark-up syntax and constructs inside text
using font-lock-doc-face; ie, documentation comments and strings in
programming modes.
* lisp/font-lock.el (font-lock-doc-markup-face): New face.
* lisp/cus-theme.el (custom-theme--listed-faces): Add it to the list.
* doc/lispref/modes.texi (Faces for Font Lock): Document it.
* etc/NEWS: Mention it.
* lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): Check
the language has multi-line strings before calling
c-ml-string-opener-at-or-around-point.
* lisp/international/mule-util.el (filepos-to-bufferpos): Give
better errors on `exact' with unknown line endings, and guess at
Unix if `approximate' (bug#36573).
(bufferpos-to-filepos): Ditto.
