* lisp/icomplete.el (icomplete-completions): Revise computation of

'xref-backend-functions' and
'semantic-symref-filepattern-alist' regardless of

unconditionally.

creation using 'djvused' too.

Always call 'find-file-noselect' rather than 'get-file-buffer' to
go through the visited-file-modtime verification every time.
Add a new `trace` setting for `track-changes-record-errors` to
record more information in order to try and help find the root
cause of errors.

`key-select-translation` so as to stick to the `key-translate-` prefix.
Silence compilation warning.
* lisp/keymap.el (key-translate): Add an interactive form, prompting for
keys to translate, and update docstring to reflect this.
(key-translate-selection-function): New custom option.
(key-select-translation): New function, default value of above option.
(key-translate-remove): New command, for removing entries from
`keyboard-translate-table'.

careful with `help-enable-completion-autoload` so we don't load
a package in cases where we already know it won't impact the result.
* lisp/files.el (save-some-buffers-action-alist): New M-~ entry.
(save-some-buffers):
* doc/emacs/files.texi (Save Commands):

Teach term the difference between an unset foreground or
background color and a color that happens to match an existing
color. This way, when we insert text after a color
reset:(e.g. from an SGR0), we insert it without :foreground or
:background (whichever we've reset) face properties, allowing
that inserted text to inherit the colors of the underlying face.
This way, if we change, e.g., the background color of a buffer,
the background color of already-inserted text from the term
child changes along with that of the buffer instead of being
"locked" to whatever the background color of the buffer was at
the time the text was inserted.
This change aligns term.el with other terminal emulators.
* lisp/term.el (term-ansi-current-color):
(term--color-as-hex): track nil fg, bg colors
* lisp/help-fns.el (xref-backend-references):
New context-dependent override. Don't call project-current and

project-vc-external-roots-function then.
* lisp/help-fns.el (help-fns--setup-xref-backend):
New function (bug#69462).

accept the symbol 'permanent-local', meaning that the variable is
permanent but not marked as automatically buffer-local.

above change.
* test/lisp/custom-tests.el
(custom-tests-defcustom-:local-keyword): New test.
`package-initialize` is used to initialize the whole machinery needed
to list/download/install/remove packages, whereas here we only need to use
the installed packages.
