record more information in order to try and help find the root
cause of errors.

(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.

(save-some-buffers):
* doc/emacs/files.texi (Save Commands):

specs which produce stretch glyphs wider than the window when
lines are truncated. (Bug#73600)
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

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

dired-do-open.

user-error when the buffer is narrowed.

user-error when the buffer is narrowed.
* lisp/emacs-lisp/bytecomp.el (bytecomp--custom-declare): Warn about
invalid values for the defcustom :local keyword.

(bytecomp-test-defcustom-local): New test.
* lisp/custom.el (custom-declare-variable): Make the :local keyword
accept the symbol 'permanent-local', meaning that the variable is
permanent but not marked as automatically buffer-local.
(defcustom):
* doc/lispref/customize.texi (Variable Definitions): Document the
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.
* lisp/vc/diff-mode.el (diff-delete-other-hunks): New
command (bug#73387).
(diff-mode-map): Bind the new command to C-c RET n.

When _FORTIFY_SOURCE is defined mingw-w64 provides an inline definition
of read in io.h. This makes our previous redirection to sys_read
ineffective. The prototype of sys_read is now required because we don't
touch the prototype of read.
* nt/inc/ms-w32.h (read): Move the redirection after io.h. Add prototype
for sys_read (Bug#73444)
* etc/ERC-NEWS: Announce removal of troublesome key binding first
introduced in ERC 5.6 as part of the `erc-fill-wrap' module.
* lisp/erc/erc-fill.el (erc-fill-wrap-mode-map): Remove key binding for
`erc-fill-wrap-cycle-visual-movement'.

(erc-fill-wrap-visual-keys--prompt): Replace "C-c a" key simulations.
(Bug#73553)
* lisp/erc/erc-nicks.el (erc-nicks-mode, erc-nicks-enable)
(erc-nicks-disable): Use correct name for `track' module hook.
(erc-nicks--check-normals): Remove falsity from doc string.

when optional COUNT is nil.
(erc-track-modified-channels): Use new name for preferred face-finding
function.
(erc-track--get-faces-in-current-message, erc-track--collect-faces-in):
Rename former to latter to better reflect expanded utility, which now
includes spanning gaps, including newlines and indentation that may be
lacking in face-related properties.
* test/lisp/erc/erc-track-tests.el (erc-track--collect-faces-in): New
test. (Bug#73443)
* etc/ERC-NEWS: Entry mentioning `erc-keep-place-indicator-truncation'.
* lisp/erc/erc-goodies.el (erc-keep-place-indicator-truncation): New
option. Something like this should have accompanied the module's
introduction.
(erc-keep-place-indicator-mode, erc-keep-place-indicator-enable)

first introduced by bug#59943.
(erc--keep-place-move-hook): New variable.
(erc--keep-place-indicator-adjust-on-clear): New function.
(erc-keep-place-move): Try to ensure the overlay resides at the
