* lisp/erc/erc-track.el (erc-modified-channels-alist): Clarify what
the list contains. Add references to variables and functions involved
in displaying tracked buffers from this list.
(erc-make-mode-line-buffer-name): Describe exactly the algorithm, and
reference custom variables that influence it.
* lisp/erc/erc-track.el (erc-modified-channels-alist): Fix the
docstring: each element is a dotted list where the last cdr is
sometimes a proper list, making the element only sometimes a proper
list.
Prefer mailing lists to newgroups.
(History of Emacs): Rename from "Status of Emacs".
Move XEmacs node here.
(Emacs for other operating systems): Merge all the "non-Unix"
systems into a single node.
* lisp/finder.el (finder-compile-keywords): Now that 'version' is
set for more files, it is no longer necessary to check that we have
a version when picking the file from which to take the description.
Doing so caused built-in packages (where the version is known) to have
their package description taken from the last .el file that matched the
file name pattern, usually the last source file in the sub-directory.
This bug was introduced in July 2019 and first released in Emacs 27.1.
Thanks to Michael Albinus for reviewing this patch.
This fixes bug #47468.
* lisp/progmodes/cc-engine.el (c-looking-at-inexpr-block): While searching
backwards for "->" which is a type indicating operator, disallow also commas.
Also optimize a loop over several line doc-comments.
* lisp/progmodes/cc-fonts.el (c-font-lock-doc-comments): New variable
comment-mid, used as the starting point for applying c-doc-face-name in a
line comments. In block comments, apply this face not from `comment-beg' but
from `region-beg', no earlier than the start of the fontification region.
* lisp/erc/erc-stamp.el (erc-insert-timestamp-right): Use latest
buffer's window's width to position the timestamp, if both
`erc-timestamp-right-column' and `erc-fill-column' are not set (or
`erc-fill-mode' is off). This is what the documentation says, but was
not implemented. Also fix the bug of using selected window's width
instead of the (or some) window showing the buffer. The latest
window's width is saved in `erc-timestamp-last-window-width' and used
when the buffer is no more shown. In case the buffer was never shown,
which I'm not sure can happen, either use `fill-column' if set, or
give up on aligning and just output the timestamp (modulo the kludge)
right after message text. While here, fix the off by one calculation
of point start when the reference is the window's width.
* lisp/erc/erc-ibuffer.el (erc-modified): Don't use `length' on dotted
lists (and not even to test if there is more than one element, for
that matter). Use `cdr' instead.
* doc/emacs/book-spine.texi: New file: the printed book spine.
* doc/emacs/back.texi: New file: the backcover text for the
printed book.
* doc/emacs/emacs.texi: Update ISBN.
* lisp/progmodes/cc-langs.el (c-<>-arglist-kwds): Add const_cast,
dynamic_cast, reinterpret_cast and static_cast into this lang const.
* lisp/progmodes/cc-engine.el (c-clear-<-pair-props, c-clear->-pair-props)
(c-clear-<-pair-props-if-match-after, c-clear->-pair-props-if-match-before)
(c-forward-<>-arglist-recur):
Invalidate caches with c-trunctate-lit-pos-cache.
(c-forward-<>-arglist-recur): If in a matching <...> expression, the < has a
syntax-table property, but the > not, remove that property.
This was mistakenly applied to NEWS.27 on the master branch in
2021-05-09 "; Fix decoded-time-set-defaults typo in NEWS.27."
but that has now been reverted (bug#48298).
* src/w32common.h: Rename OS_* to OS_SUBTYPE__*, as w32 API
headers started defining OS_NT, which breaks the use of the
enumeration. All users changed. (Bug#48303)
The code for this is the symbol 'n', which is usually spelled as '\n'
here, not the character ?\n.
* doc/misc/autotype.texi (Skeleton Language): Fix item for
newline-and-indent.
