* lisp/jit-lock.el (jit-lock--antiblink-l-b-p): Rename from
jit-lock--antiblink-l-l-b.
(jit-lock--antiblink-grace-timer): Add period to docstring.
(jit-lock--antiblink-post-command): Rework after Stefan's
comments.

* lisp/jit-lock.el (jit-lock-antiblink-grace): New variable.
(jit-lock--antiblink-grace-timer, jit-lock--antiblink-l-l-b)
(jit-lock--antiblink-i-s-o-c): New helpers.
(jit-lock-mode): Tweak post-command-hook and
jit-lock-context-timer.
(jit-lock--antiblink-post-command): New helper.

* lisp/mouse.el (mouse-drag-region-rectangle):
Enable transient-mark-mode during selection (bug#38431).

* test/lisp/net/tramp-tests.el (tramp-test10-write-region)
(tramp-test10-write-region-file-precious-flag)
(tramp-test34-connection-local-variables)
(tramp-test36-vc-registered): Let-bind `inhibit-message'.

* lisp/ibuf-ext.el (ibuffer-mark-by-content-regexp): Use `cl-dolist'
instead of `cl-some' to avoid a run-time dependency on cl-lib that
triggers an unreported bug similar to bug#38430.

* lisp/ibuf-ext.el (ibuffer-generate-filter-groups): Don't call
`cl-values-list'.  Our implementation of that function just
checks that its argument is a list, and then returns it.  In
this specific case, the argument is guaranteed to be a list.

Make the rectangular selection work better with
display-line-numbers-mode and side-by-side windows.
Also make the mouse track the text cursor in a consistent way.

* lisp/mouse.el (mouse--rectangle-track-cursor): Added constant.
(mouse-drag-region-rectangle): Take the line-number width into
account, and use window-relative columns.  Track either the cursor or
rectangle corner with more care.

Use setq to set buffer-local values of truncate-lines and buffer-undo-list.
This will prevent leaking of let-bound values to buffer-local values
of the minibuffer.

* doc/misc/gnus.texi (Tabbed Interface): New node.  (bug#37998)

* lisp/subr.el (read-char-from-minibuffer-insert-other)
(y-or-n-p-insert-other): Use discard-input in case of user mistake.
(do-after-load-evaluation): Add discard-input before calling 'message',
so in case of the active minibuffer, calling minibuffer-message will allow
sit-for to wait the complete timeout, because discard-input will discard
all initial events that prevent sit-for from waiting during startup.

In particular, with these unterminated quotes on each of two adjacent lines,
the following text was spuriously fontified with string face.

* lisp/progmodes/cc-defs.el
(c-search-backward-char-property-with-value-on-char): New macro.

* lisp/progmodes/cc-mode.el (c-clear-string-fences): Check whether there is an
unmatched quote at a lower buffer position which should match the current
quote, rather than wrongly assuming the latter is unmatched and marking it
with a punctuation syntax.
(c-font-lock-fontify-region): Ensure all pertinent parts of the buffer have
string fence properties applied before performing any syntactic operations on
it; in particular, this applies to a quote at an earlier buffer position which
"matches" one inside the region about to be fontified.

* lisp/image.el (image-increase-size, image-decrease-size):
Add optional arg position.
(image-mouse-increase-size, image-mouse-decrease-size):
Use '(point-marker)' for arg position.
(image--get-image): Use get-char-property from position if non-nil,
and its buffer.
(image--get-imagemagick-and-warn, image--change-size):
Add optional arg position.

* lisp/emacs-lisp/timer.el (debounce, debounce-reduce): Revert macro addition.
https://lists.gnu.org/archive/html/emacs-devel/2019-11/msg01133.html

* lisp/image.el (image-increase-size, image-decrease-size):
Use run-with-idle-timer.
(image--change-size): Rename back from image--change-size-function.

* lisp/image-mode.el (image-mode--setup-mode): Remove hooks
window-size-change-functions and window-selection-change-functions (bug#32672)
(image-fit-to-window): Rename from image--window-change-function.
(image--window-state-change): Rename from image--window-change.
Use run-with-idle-timer.

* lisp/vc/vc-hg.el (vc-read-revision): Declare.

* doc/emacs/maintaining.texi (Switching Branches)
(Pulling / Pushing, Merging): Fix markup of shell commands.

* lisp/vc/vc-hg.el (vc-hg-merge-branch): Prompt for revision to merge.
(vc-hg-revision-table): Use branches, tags and bookmarks as competion
candidates.

* etc/NEWS: Mention changes of vc-hg.el

* doc/emacs/maintaining.texi (Switching Branches): Mention 'hg update'
command.

(ediff-even-diff-B, ediff-even-diff-C)
(ediff-even-diff-Ancestor, ediff-odd-diff-A)
(ediff-odd-diff-B, ediff-odd-diff-C)
(ediff-odd-diff-Ancestor):
* lisp/vc/diff-mode.el (diff-header, diff-file-header)
(diff-removed, diff-added): Make sure all definitions of faces
have the same value of the ':extend' property, otherwise
customizing background color or underline etc. attributes of
these faces on some displays will produce effects different
from other displays.

* src/image.c (lookup_image): Move call to image_set_transform after
postprocess_image.
(image_create_x_image_and_pixmap_1): Use new function.
(image_set_transform): Apply the transform to the mask too.

so the transparency is honoured.
(x_draw_image_foreground_1): Use x_composite_image.

This makes the accessors into (inlined) functions (instead of macros),
which simplifies some uses, and it makes the gnus-info-set-<foo>
macros redundant since we can use `setf` instead.  Remove them and
update all users.

(gnus-info-group, gnus-info-rank, gnus-info-read, gnus-info-marks)
(gnus-info-method, gnus-info-params): Auto-defined by defstruct.
(gnus-info-level, gnus-info-score): Define as a function.  Add gv-setter.
(gnus-info-set-group, gnus-info-set-rank, gnus-info-set-read): Remove,
use `setf` instead.

Use the `extend` arg of `gnus-info-set-method`.
(gnus-group-sort-selected-flat): eta-reduce.

The `sgml-syntax-propertize-rules` rely on the `sgml--syntax-propertize-ppss`
setup by `sgml-syntax-propertize` so it is not correct/safe to use
them directly like html used to do.

Change `sgml-syntax-propertize` so it can be used by mhtml,
and then adjust mhtml-mode accordingly.

* lisp/textmodes/mhtml-mode.el: Remove redundant `eval-and-compile`.
Only require cl-lib at compile-time.
(mhtml--syntax-propertize): New const, extracted from mhtml-syntax-propertize.
(mhtml-syntax-propertize): Use `sgml-syntax-propertize`.

* lisp/textmodes/sgml-mode.el (sgml--syntax-propertize): New const,
extracted from sgml-syntax-propertize.
(sgml-syntax-propertize): Add optional `rules-function` arg.

that IPv6 addresses are returned from network-interface-list, test
nsm-should check and nsm-network-same-subnet for IPv6 as well.

* lisp/vc/vc-hg.el (vc-hg-print-log): Support 'with-diff'
invocation of "C-1 C-x v L".

(Bug#38407)

* doc/emacs/killing.texi (Other Kill Commands): Document
'zap-up-to-char'.

* lisp/simple.el (zap-to-char): Mention 'zap-up-to-char' in
the doc string.  (Bug#38392)

* lisp/vc/vc-svn.el (vc-svn-print-log): Support 'with-diff'

warnings, and 'void-variable' errors where the variable has confusable
quote characters in it.

New test.

Revert commits from 2018-01-28 "Fix round tripping of read->print for
symbols with strange quotes", and 2017-07-22 "Signal error for symbol
names with strange quotes (Bug#2967)".
* etc/NEWS: Remove corresponding entries.
* src/character.c (confusable_symbol_character_p):

  * lisp/dired-aux.el (dired-isearch-filenames-end)
  (dired-isearch-filenames, dired-isearch-filenames-regexp): Use
  temporary local variable for dired-isearch-filenames instead of
  custom-reevaluate-setting (Bug#30187).  Without this fix, the value
  set in .emacs with plain setq would be lost after one isearch.
