* lisp/frame.el (undelete-frame): New command.
(undelete-frame--handle-delete-frame): New auxiliary function.
(undelete-frame--deleted-frames): New auxiliary variables.
(undelete-frame-mode): New minor mode.
(ctl-x-5-map): Bind the new command.
* etc/NEWS: Document the new command and minor mode.
* src/frame.c (Fdelete_frame): Update docstring, and mention the
minor mode.
* lisp/menu-bar.el (menu-bar-file-menu): Add an entry for the
new command.
* doc/emacs/frames.tex (Frame Commands): Document the new command
and minor mode.
See bug#51883.
The basic idea is, we're moving the setting/unsetting of
`gnus-registry-enabled' so that it is a more reliable indicator of
whether the registry is actually available or not.
* lisp/gnus/gnus-registry.el (gnus-registry-load): Move the setting of
`gnus-registry-enabled' here, after we're sure the registry actually
has been loaded.
(gnus-registry-initialize): Move it out of here. All this function
does is conditionally call `gnus-registry-load'.
(gnus-registry-register-message-ids): Only check
`gnus-registry-enabled', since we'd more confident about this
now. Sort checks in order of increasing complexity.
(gnus-registry-clear): Unset `gnus-registry-enabled'.
(gnus-registry-install-hooks): This function should only install
hooks, not set variables.
(gnus-registry-unload-hook): Change the unload hook to call
`gnus-registry-clear', as that will do all the necessary
work (including calling `gnus-registry-unload-hook')
* lisp/isearch.el (isearch-emoji-by-name): Add a new command to insert
Emoji characters into incremental search strings. (Bug#52605)
(isearch-mode-map): Bind it to 'C-x 8 e RET'.
(isearch-menu-bar-map): Add it to the menu bar.
* doc/emacs/search.texi (Special Isearch): Update the documentation to
mention the new command.
* etc/NEWS: And advertise it.
Lambda-lifted variables (ones passed explicitly to lambda-lifted
functions) that are also captured in an outer closure and shadowed
were renamed incorrectly (bug#51982).
Reported by Paul Pogonyshev.
* lisp/emacs-lisp/cconv.el (cconv--lifted-arg): New.
(cconv-convert): Provide correct definiens for the closed-over
variable.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
* test/lisp/emacs-lisp/cconv-tests.el (cconv-tests--intern-all)
(cconv-closure-convert-remap-var): Add tests.
(cherry picked from commit 45252ad8f9)
* lisp/eshell/esh-opt.el (eshell--split-switch): New function.
(eshell-set-option): Allow setting a supplied value instead of always
consuming from 'eshell--args'.
(eshell--process-option): Support consuming option values specified as
a single token.
(eshell--process-args): For short options, pass full switch token to
'eshell--process-option'.
* test/lisp/eshell/esh-opt-tests.el (esh-opt-process-args-test): Fix
test.
(test-eshell-eval-using-options): Add tests for various types of
options.
* doc/misc/eshell.texi (Defining new built-in commands): New
subsection, describe how to use 'eshell-eval-using-options'.
* etc/NEWS: Announce the change.
* lisp/gnus/gnus-art.el (gnus-treat-emphasize): Don't do emphasis
in text/html parts, because this leads to mis-filled text
(especially with *...* that's boldified, which typically becomes
much wider).
* lisp/window.el (display-comint-buffer-action):
Use display-buffer--same-window-action as the default value.
* lisp/progmodes/sh-script.el (sh-show-shell):
* lisp/shell.el (shell): Add display-comint-buffer-action to pop-to-buffer.
* lisp/progmodes/project.el (project-shell, project-eshell): Use
`bound-and-true-p display-comint-buffer-action' for backward-compatibility.

When calling outline-on-heading-p, set its argument INVISIBLE-OK to t,
so when <backtab> (bound to outline-cycle-buffer) hides the current outline
at a deep level, <backtab> should continue cycling outlines even when
the current outline heading is invisible. It worked this way before
the recent change that moved cycling keys from font-lock text properties
to outline-minor-mode keymap with :filter.
To be able to use outline-minor-mode-cycle keys in diff-mode,
outline-minor-mode should be higher in minor-mode-map-alist,
and a new variable diff-mode-read-only should be set
when the diff-mode buffer is read-only.
https://lists.gnu.org/archive/html/emacs-devel/2022-01/msg00740.html
* lisp/vc/diff-mode.el: Add diff-mode-read-only to minor-mode-map-alist.
(diff-mode-read-only): New buffer-local variable.
(diff-mode): Set diff-mode-read-only to t when buffer-read-only is non-nil.
Update diff-mode-read-only in read-only-mode-hook.
Remove buffer-read-only from minor-mode-overriding-map-alist.
Remove view-mode-hook because now view-mode is higher than
diff-mode-read-only in minor-mode-map-alist.
* lisp/vc/vc-git.el (vc-git-stash-show):
* lisp/vc/vc.el (vc-diff-internal): Set buffer-read-only to t
before calling diff-mode that will set diff-mode-read-only.
Instead of adding font-lock text property 'keymap' with
outline-minor-mode-cycle on headings in outline-minor-mode,
check for outline-minor-mode-cycle and outline-on-heading-p
in :filter on keys from the keymap of outline-minor-mode.
https://lists.gnu.org/archive/html/emacs-devel/2022-01/msg00180.html
(outline-minor-mode-cycle--bind): Add a condition on outline-minor-mode-cycle
and outline-on-heading-p in :filter.
(outline-font-lock-keywords): Remove if-branches for outline-minor-mode-cycle
that added keymap.
(outline-minor-mode-highlight-buffer): Don't put keymap on overlays.
(outline-minor-mode): Rewrite :keymap setting to rely on
easy-mmode-define-keymap, and add :inherit outline-minor-mode-cycle-map.
Don't check for outline-minor-mode-cycle to add font-lock keywords.
(outline--insert-open-button, outline--insert-close-button):
Remove :parent outline-minor-mode-cycle-map.
* doc/lispref/display.texi (Face Attributes): Document new
`:position' property of the `:underline' attribute.
* etc/NEWS: Announce new property.
* lisp/cus-face.el (custom-face-attributes): Implement
customization for new face attribute.
* src/dispextern.h (struct face): New fields
`underline_pixels_above_descent_line' and
`underline_at_descent_line_p'.
* src/haikuterm.c (haiku_draw_text_decoration):
* src/nsterm.m (ns_draw_text_decoration):
* src/w32term.c (w32_draw_glyph_string):
* src/xterm.c (x_draw_glyph_string): Respect new face fields.
* src/xfaces.c (realize_gui_face): Handle new `:position'
keyword.
(syms_of_xfaces): New symbol `:position'.
* lisp/files.el (save-some-buffers): Only check the
`save-some-buffers-function` property on functions from
`save-some-buffers-default-predicate` since callers which provide
a `pred` argument can arrange to compute `pred` themselves if needed.
* test/lisp/files-tests.el (files-tests-buffer-offer-save): Don't test
with `pred` set to `save-some-buffers-root` since it's not an
appropriate function for that any more.
Believe it or not, people actually want this, because it makes
Emacs behave closer to some other editors such as WPS Office.
* lisp/term/x-win.el
(x-display-cursor-at-start-of-preedit-string): New user option.
(x-preedit-text): Respect new option.
* lisp/elide-head.el (elide-head-mode): New minor mode. (Bug#52980)
(elide-head--delete-overlay, elide-head--show)

(elide-head, elide-head-show): ... here. Make obsolete in favor
of elide-head-mode.
(elide-head-headers-to-hide): Doc fix.
* test/lisp/elide-head-tests.el (ert-x): Require.
