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.

* 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.

* lisp/files.el (save-some-buffers): Only check the

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.

meaningful on X, renames it `preedit-text', and documents it.

`preedit-text'.
* lisp/term/pgtk-win.el (pgtk-preedit-text): Bind to
