* lisp/dired-aux.el (dired-read-shell-command): Use
dired-guess-shell-command unconditionally, as it is now always
available.
(dired-do-shell-command): Doc fix; dired-guess is always available.

where appropriate.
(python-font-lock-extend-region): New function.
(python-mode): Set `python-font-lock-extend-region' to
`font-lock-extend-after-change-region-function'.
* lisp/progmodes/python.el (python-nav-beginning-of-block-regexp):
New variable.
(python-hideshow-forward-sexp-function): Change to call
`python-nav-end-of-block'.

(python-info-looking-at-beginning-of-block): New function to be
used as LOOKING-AT-BLOCK-START-P-FUNC in `hs-special-modes-alist'.

(python-hideshow-hide-levels-3, python-hideshow-hide-levels-4)
(python-hideshow-hide-all-1, python-hideshow-hide-all-2)
(python-hideshow-hide-all-3, python-hideshow-hide-block-1): New
tests (bug#56635).
* lisp/emacs-lisp/byte-opt.el (byte-optimize-and, byte-optimize-or):
Rewrite. Avoid branching on arguments statically known to be true or
false, and hoist code out to an unconditional prefix when possible.
Recognise some more special cases:
(if X nil t) -> (not X)
(if X t) -> (not (not X))
(if X t nil) -> (not (not X))
(if VAR VAR X...) -> (or VAR (progn X...))
* lisp/emacs-lisp/byte-opt.el (byte-opt-negate): New.
(byte-optimize-if): Add transformations above and refactor.
(byte-optimize-while): Better static nil-detection.
* lisp/emacs-lisp/byte-opt.el (byte-opt--bool-value-form): New.
(byte-compile-trueconstp, byte-compile-nilconstp): Determine a static
nil or non-nil result in more cases. These functions have grown and
are no longer defsubst.
* src/xfns.c (setup_xi_event_mask): Stop selecting for device
hierarchy events.
* src/xterm.c (xi_select_hierarchy_events, x_term_init): Select
those here instead, on the default root window.
* doc/misc/gnus.texi (The problem of spam): Don't explain what
spam is; there is no need for that in 2022. Don't explain
limitations of obsolete software TMDA; it's website has stopped
working but seems to have been updated last in 2007.
(Thwarting Email Spam, Anti-Spam Basics)
(Spam Package Configuration Examples): Prefer "spam" to "UCE".
(The problem of spam): Use example.org in example.
(SpamAssassin, Hashcash): Improve wording.
* src/fringe.c (large_circle_bits): New variable.
(standard_bitmaps): Add large_circle_bits.

* lisp/cus-edit.el (widget-fringe-bitmap-prompt-value-history): New
variable.
(fringe-bitmap): New widget.
* lisp/bookmark.el (bookmark-set-fringe-mark): Obsolete in favor of...
(bookmark-fringe-mark): ... this.
(bookmark-fringe-mark): Rename this fringe bitmap to...
(bookmark-mark): ... and change it to look like a bookmark.
(bookmark-face): Don't set the ':background' of the face. Instead,
set ':distant-foreground'.
(bookmark--set-fringe-mark, bookmark--remove-fringe-mark)
(bookmark-store, bookmark--jump-via): Consult the
'bookmark-fringe-mark' option.
* doc/lispref/customize.texi (Simple Types): Document 'fringe-bitmap'
type.
* doc/lispref/display.texi (Fringe Bitmaps): Mention 'large-circle'.
* etc/NEWS: Announce this change (bug#56896).
* lisp/eshell/esh-cmd.el (eshell-rewrite-if-command): Fix misplaced
't' symbol; it should be passed to 'eshell-invokify-arg'.
(eshell-do-eval): Pass 'synchronous-p' to recursive calls in some
missing cases.
* test/lisp/eshell/esh-cmd-tests.el (esh-cmd-test/if-statement,
(esh-cmd-test/if-else-statement)
(esh-cmd-test/if-else-statement-lisp-form)
(esh-cmd-test/if-else-statement-lisp-form-2)
(esh-cmd-test/if-else-statement-ext-cmd)
(esh-cmd-test/unless-statement)
(esh-cmd-test/unless-else-statement)
(esh-cmd-test/unless-else-statement-lisp-form)
(esh-cmd-test/unless-else-statement-ext-cmd): Use
'eshell-command-result-equal'.
This was formerly named 'eshell-command-result-p', but "result" isn't
quite the right terminology, since this function specifically tested
the output of a command, not its Lisp result (as
'eshell-command-result' would return).
* test/lisp/eshell/eshell-tests-helpers.el (eshell-insert-command):
Provide a more-complete docstring.
(eshell-match-result): Rename to...
(eshell-match-output): ... this.
(eshell-match-output--explainer): New function.
(eshell-command-result-p): Rename to...
(eshell-match-command-output): ... this.
