* 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.

Allow evaluating Python code across machines

* python.el (python-shell-send-string): Ensure that the temporary file
is created in the host running the Python process (bug#50057).

Fix unwarranted point movement after C-g

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)

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.

completion frontends to opt-in an time-saving optimization by some
completions styles, such as the 'flex' and 'pcm' styles.

The variable must be set by the frontend to a unique value around a

* lisp/emacs-lisp/easymenu.el (easy-menu-do-define): Fix bug#50051

(map-merge-with): Ditto.  This ensures that FUNCTION is called

map-merge, thus achieving greater overall predictability.

* test/lisp/emacs-lisp/map-tests.el (test-map-merge)

(tramp-smb-handle-file-writable-p)
(tramp-smb-handle-insert-directory)
(tramp-smb-handle-start-file-process, )
(tramp-smb-read-file-entry): Use `tramp-compat-string-search'.

Make icalendar parse multi-line items correctly

Parse multi-line items correctly (bug#37887).

Fix icalendar-import-file prompt

* lisp/calendar/icalendar.el (icalendar-import-file): Fix prompt.

Make gnus-icalendar-event-from-ical more robust

* lisp/gnus/gnus-icalendar.el (gnus-icalendar-event-from-ical):
Don't bug out on nil UIDs.

Drop redundant keywords in .desktop files.

The Freedesktop.org Desktop Entry spec says, “The values [of
Keywords]… should not be redundant with the values of Name or
GenericName”.

* etc/emacs.desktop, etc/emacsclient.desktop (Keywords): Remove
keywords that are duplicated from the GenericName field.

Hint that emacsclient.desktop should match a search for “emacsclient”

This is necessary to get the Gnome desktop to show “Emacs (Client)”
when the user searches for “emacsclient”.

* etc/emacsclient.desktop, emacsclient-mail.desktop (Keywords): Add
“emacsclient”.

Valid quoting in .desktop files

* etc/emacsclient.desktop, emacsclient-mail.desktop (Exec): Quote
according to the rules in the Freedesktop.org Desktop Entry
Specification.

Mark marked images in Image-Dired mode

* lisp/image-dired.el (image-dired-thumb-update-marks): New
function that makes the marks visible in the thumbnail buffer
(bug#49988).
(image-dired-thumb-margin, image-dired-thumb-mark-color): New user
options.

Let image-dired-mouse-toggle-mark act on active region

* lisp/image-dired.el (image-dired-mouse-toggle-mark): When region is
active, then toggle marks of all images within (bug#49987).
(image-dired-mouse-toggle-mark-1): Separated out into function.

; Fix typos

* lisp/replace.el (perform-replace): Use 'remove-function' (bug#49963).

Don't let-bind the value of 'isearch-filter-predicate' to protect
from changing the global value, since with a buffer-local value
it still changes the global value.  So after using 'add-function' on the
global value of 'isearch-filter-predicate', call 'remove-function' to remove
'region-filter' from the global value in 'unwind-protect'.

Use ### for outline headings in shell-script-mode

* lisp/progmodes/sh-script.el (sh-mode): Use ### for outline headings.
This aligns it more with emacs-lisp-mode headings.

Add support for outlining in shell-script-mode

(gnus-topic-prepare-topic): Use it.

More robust auto-detect of grep-highlight-matches (bug#49978)

* lisp/progmodes/grep.el (grep-compute-defaults):
Don't require "grep --help" to finish with exit status 0 (BSD grep
does not) and check the output in a slightly more robust way.

Add a new command `revert-buffer-quick'

* doc/emacs/files.texi (Reverting): Document it.
* lisp/bindings.el (ctl-x-x-map): Bind `C-x x g' to
`revert-buffer-quick' instead.

* lisp/files.el (revert-buffer-quick-short-answers): New user option.
(revert-buffer-quick): New command (bug#49869).

Fix nnrss-get-namespace-prefix (bug#34685)

* lisp/gnus/nnrss.el (nnrss-get-namespace-prefix): Use the car of
parameter el to match what dom-search expects.
* test/lisp/gnus/nnrss-tests.el (test-nnrss-xml): Adjust to what
xml-parse-region produces (bug#34685).

Tramp string-search and string-replace compatibility functions

Add a `string-search` compatibility function for use in Tramp with
Emacs version prior to 28, and fix the existing `string-replace`
compatibility function so that it uses the right semantics.

Use case-sensitive matching and literal replacement.
(tramp-compat-string-search): New function.
* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-file-name-all-completions):
* lisp/net/tramp-sh.el (tramp-sh-handle-file-name-all-completions)
(tramp-do-copy-or-rename-file-out-of-band)
(tramp-sh-handle-make-process, tramp-sh-handle-process-file):
* lisp/net/tramp.el (tramp-handle-make-process):
Use `tramp-compat-string-search` instead of `string-match-p`.

* lisp/emacs-lisp/cl-generic.el: Try and fix bug#49866

(cl-generic-generalizers): Remember the specializers that match
a given value.
(cl--generic-eql-generalizer): Adjust accordingly.

* test/lisp/emacs-lisp/cl-generic-tests.el (cl-generic-test-01-eql):
Add corresponding test.

* lisp/emacs-lisp/package.el (package-buffer-info): Fix typo

* lisp/emacs-lisp/package.el (package-buffer-info): Use lm-maintainers

Avoid the now obsolete `lm-maintainer`.

* lisp/ffap.el (ffap-read-file-or-url): Put point at the end of
URLs (bug#44822).
(ffap--url-file-handler): Remove hack for default dirs.

Forestall "Selected deleted buffer" in url-http-generic-filter

* lisp/url/url-http.el (url-http-generic-filter): Check that
corresponding buffer is still live before using it (bug#49928).

Make xterm-set-window-title more robust

* lisp/term/xterm.el (xterm-set-window-title): Don't do anything
on graphic displays (bug#49932).

Fix tmm-get-keymap under native-compile

* lisp/tmm.el (tmm-get-keymap): Make this work under
natively-compiled Emacsen (and with lexical binding, too) (bug#49953).

Further fixes for package-quickstart-refresh printing

* lisp/emacs-lisp/package.el (package-quickstart-refresh): Really
ensure that the structures aren't shortened (bug#49924).

Fix last commit of tramp.el

Fix freeze on OpenBSD when reading the SECONDARY selection

* configure.ac (NSIG_MINIMUM): OpenBSD doesn't have a broken SIGIO
any more (bug#29170).  Backport fix from the current OpenBSD port
tree.

Add test for nnrss

* test/lisp/gnus/nnrss-tests.el (test-nnrss-xml): New test (bug#34685).

Use `let*` instead of `let`.

Use string-search instead of string-match[-p]

`string-search` is easier to understand, less error-prone, much
faster, does not pollute the regexp cache, and does not mutate global
state.  Use it where applicable and obviously safe (erring on the
conservative side).
