* src/xfaces.c (face_at_string_position): Revert the last
change, as it cannot possibly solve bug#38563.
* src/xdisp.c (face_at_pos): Fix a typo made during last
change here, which broke face merging for display strings.
(Bug#38633)
Better handling of tabs scrolled to the left.
Don't scroll tabs that are already visible.
Remove setq of buffer-undo-list because undo is disabled
anyway in internal buffers with name " *temp*".
* lisp/vc/diff.el (diff-buffers): New command.
(diff, diff-no-select, diff-file-local-copy): Improve docstrings.
* doc/emacs/files.texi:
* etc/NEWS: Document new command, and the previously-undocumented
ability for 'diff' to compare buffers.
* doc/lispref/internals.texi (Garbage Collection)
(Pure Storage):
* src/alloc.c (Fgarbage_collect): Update the documentation of
pure-space overflow for when pdumper is used. (Bug#38492)
* src/emacs.c (Fdump_emacs): Remove stray closing brace that
breaks the build when configured with --with-dumping=unexec on
GNU/Linux. (Apparently everybody is using pdumper now.)
I introduced the bug in 2019-07-09T00:50:39Z!eggert@cs.ucla.edu.
* lisp/jsonrpc.el (initialize-instance jsonrpc-process-connection):
Use buffer-disable-undo in stdout and stderr buffers.
* lisp/jsonrpc.el (Version): Bump to 1.0.9
The `not' and `intersection' forms, and `or' inside these forms,
now accept characters and single-character strings as arguments.
Previously, they had to be wrapped in `any' forms.
This does not add expressive power but is a convenience and is easily
understood.
* doc/lispref/searching.texi (Rx Constructs): Amend the documentation.
* etc/NEWS: Announce the change.
* lisp/emacs-lisp/rx.el (rx--charset-p, rx--translate-not)
(rx--charset-intervals, rx): Accept characters and 1-char strings in
more places.
* test/lisp/emacs-lisp/rx-tests.el (rx-not, rx-charset-or)
(rx-def-in-charset-or, rx-intersection): Test the change.
* lisp/help.el (help-uni-confusables, help-uni-confusables-regexp):
Rename from uni-confusable and uni-confusables-regexp, respectively.
(help-uni-confusable-suggestions): Use ngettext. Use new variable
name.
* lisp/emacs-lisp/lisp-mode.el (lisp--match-confusable-symbol-character):
Use new variable name.
* src/xdisp.c (face_at_pos): Revert previous change that
rejected the underlying face if it failed the filtering
criteria.
* src/xfaces.c (face_at_string_position): Reset the base face's
attribute used for filtering faces if the attribute is t.
(Bug#38563)
* src/xdisp.c (face_at_pos): Reject the face returned by
'underlying_face_id' when we are filtering by face attribute,
and that attribute's value fails the filter test. (Bug#38563)
The strings contained in gpg keys can contain UTF-8 data, but can also
use percent-escapes to encode non-ASCII chars. When converting those
escapes, use 'raw-text' coding system rather than 'string-to-unibyte',
since the latter signals an error for non-ASCII characters.
* lisp/epg.el (epg--decode-percent-escape): Convert the passed
string to raw-text before treating percent escapes (Bug#38512).
Allow placing debug-on-entry on a function not-yet-defined, which
is convenient when the problem you're investigating happens while
the relevant files are loaded.
(message--old-style-completion-functions): New var.
(message-completion-function): Allow functions on
`message-completion-alist` to follow the capf protocol.
(message-completion-alist): Adjust docstring accordingly.
Simplify regexps and make them apply more liberally.
(message-expand-group): Use the capf protocol.
(completion-category-defaults): Use 'substring' completion style by
default for email addresses.
(message--bbdb-query-with-words, message--name-table): New functions.
(message-expand-name): Use them to obey `message-expand-name-standard-ui`.
These character set operations, together with `not' for set
complement, improve the compositionality of rx, and reduce duplication
in complicated cases. Named character classes are not permitted in
set operations.
* lisp/emacs-lisp/rx.el (rx--translate-any): Split into multiple
functions.
(rx--foldl, rx--parse-any, rx--generate-alt, rx--intervals-to-alt)
(rx--complement-intervals, rx--intersect-intervals)
(rx--union-intervals, rx--charset-intervals, rx--charset-union)
(rx--charset-all, rx--charset-intersection, rx--translate-union)
(rx--translate-intersection): New.
(rx--translate-not, rx--translate-form, rx--builtin-forms, rx):
Add `union' and `intersection'.
* test/lisp/emacs-lisp/rx-tests.el (rx-union ,rx-def-in-union)
(rx-intersection, rx-def-in-intersection): New tests.
* doc/lispref/searching.texi (Rx Constructs):
* etc/NEWS:
Document `union' and `intersection'.
Reinstate some of the functionality removed in commit
67a878f78f.
* src/nsimage.m (ns_image_from_XBM): Use new reverseBytes argument.
([EmacsImage initFromXBM:width:height:fg:bg:reverseBytes:]): Add
ability to reverse the contents of each byte for use with XBMs, while
still working with fringe bitmaps.
* src/nsterm.h
([EmacsImage initFromXBM:width:height:fg:bg:reverseBytes:]): Modified
function definition.
* src/nsterm.m (ns_draw_fringe_bitmap): Use new reverseBytes argument.
* lisp/dabbrev.el (dabbrev--check-all-buffers): Add new variable.
(dabbrev-completion): Lexical scoping means we can't use let to
override global variables, so use setq.
(dabbrev--reset-global-variables): Reset new variable.
(dabbrev--make-friend-buffer-list): Use new variable.
* test/lisp/dabbrev-tests.el (dabbrev-completion-test):
(dabbrev-completion-test-with-argument): New tests.
* src/minibuf.c (read_minibuf): Avoid restoring the previous buffer,
as this is already done at the end of the function; call
`add-to-history' after that point.
