* lisp/thingatpt.el (thing-at-point--beginning-of-symbol): Special
op that errors out when there's no symbols in the buffer before
point (bug#14234).
(symbol): Use it.
* lisp/ibuf-ext.el (ibuffer-do-sort-by-filename/process): Use the
same function for sorting and for displaying the
filename/process (Bug#45800).
Copyright-paperwork-exempt: yes
* lisp/thingatpt.el (thing-at-point--end-of-symbol): New function
(bug#14234).
(symbol): Use it instead of `forward-symbol', because the latter
will move to the end of the buffer even if there is no symbol
there. Instead error out like `forward-sexp' and friends.
(command-line): Don't re-evaluate the `custom-delayed-init-variables`
a second time after reading the `early-init.el` file.
(x-apply-session-resources): Set `blink-cursor-mode` rather than
`no-blinking-cursor`.
* lisp/frame.el (blink-cursor-start): Turn `blink-cursor-mode` off
if `blink-cursor-mode` was set to nil.
(blink-cursor-mode): Default to it being enabled regardless of
`window-system`.
* lisp/custom.el (custom-initialize-delay): Fox docstring now that
autoload.el preserves the `:initialize` info.
* lisp/calc/calc-embed.el (calc-embedded-set-modes): Prevent
the-language and the-display-just from being lexically bound here,
because they may be assigned using 'set'.
* lisp/gnus/message.el (message--syntax-propertize): Use the
correct Message mode syntax table to avoid having
`message-cite-prefix-regexp' trigger very heavy backtracing when
called from an abbrev context (which defines "_" as a word
constituent) (bug#45944).
* lisp/gnus/nntp.el (nntp-send-authinfo): Don't signal an
`nntp-authinfo-rejected' error, because that will stop Gnus
startup (bug#45855). Instead signal an error that will be caught
higher up.
* lisp/wid-edit.el (widget-color-match, widget-color-validate): New
functions.
(color): Use the new functions. Base size on longest defined color
name, defaulting to the longest RGB hex string.
* etc/NEWS: Document the new face (bug#45840).
* lisp/progmodes/perl-mode.el (perl-non-scalar-variable): Define new
face.
(perl-font-lock-keywords-2): Apply 'perl-non-scalar-variable' face.
* lisp/help-fns.el (keymap-name-history): Define the history
variable (bug#45879). This avoids problems in other completing
systems like Helm.

Previously, all Gnus backends returned header information by writing
nov lines into the nntp-server-buffer, which was later parsed. This
commit allows the backends to return their header information as a
list of already-parsed headers, though so far none of the backends
actually do that. The agent, cache, cloud etc. now operate on parsed
headers rather than nov text, ie. they use gnus-fetch-headers instead
of gnus-retrieve-headers.
* lisp/gnus/gnus-sum.el (gnus-fetch-headers): Handle the case in which
gnus-retrieve-headers returns headers directly.
* lisp/gnus/nnvirtual.el (nnvirtual-retrieve-headers): Use
gnus-fetch-headers rather than gnus-retrieve-headers to get headers,
meaning we're operating on already-parsed headers.
(nnvirtual-convert-headers): Remove now-unnecessary function.
(nnvirtual-update-xref-header): Rewrite to operate on parsed header.
* lisp/gnus/gnus-cloud.el (gnus-cloud-available-chunks): Use
gnus-fetch-headers instead of gnus-retrieve-headers.
* lisp/gnus/gnus-cache.el (gnus-cache-retrieve-headers): Use
gnus-fetch-headers.
(gnus-cache-braid-nov, gnus-cache-braid-heads): Delete unnecessary
functions -- we now do this work on a list of parsed headers.
* lisp/gnus/gnus-agent.el (gnus-agent-retrieve-headers): Use
gnus-fetch-headers.
(gnus-agent-braid-nov): Remove unnecessary function.
(gnus-agent-fetch-headers): Use gnus-fetch-headers.
* lisp/ibuffer.el (ibuffer--abbreviate-file-name): New function.
(filename): Use it.
* lisp/ibuf-ext.el (ibuffer-mark-by-file-name-regexp): Prefer
read-regexp over read-string for reading regexps. Determine file
name using ibuffer-buffer-file-name for consistency. Abbreviate
file name using ibuffer-directory-abbrev-alist (bug#18859).
(ede-proj-target-makefile): Give more precise type for its `rules` slot.
* lisp/cedet/ede/base.el (ede-target-list): Don't define.
(ede-project): Use `list-of` instead.
* etc/NEWS: Announce the new 'cham' input method.
* etc/HELLO: Fix the order of letters in the Cham greeting.
Remove redundant newlines (reported by Ulrich Mueller
<ulm@gentoo.org>).
* lisp/language/cham.el ("Cham"): Add input-method entry.
* lisp/leim/quail/cham.el: New file.
* lisp/international/fontset.el (setup-default-fontset): Add an
entry for Cham.
(pcase--split-pred, pcase--funcall): Adjust for `not`.
(pcase--get-macroexpander): New function.
(pcase--edebug-match-macro, pcase--make-docstring)
(pcase--macroexpand): Use it.
* lisp/emacs-lisp/radix-tree.el (radix-tree-leaf): Use it!
* doc/lispref/control.texi (The @code{pcase} macro): Document it.
* lisp/emacs-lisp/ert.el (ert--explain-equal-rec): Remove redundant test.
(blink-cursor-mode): Use `blink-cursor-check` rather than
`blink-cursor--start-idle-timer` so we check for the presence of
a frame where the cursor can be blinked before activating the idle timer.
This causes command completion to work from the project root, letting
users complete top-level folders, make targets, etc (bug#45765).
* lisp/progmodes/project.el (project-compile): Simplify using
call-interactively, as done with project(-async)-shell-command.
* lisp/window.el (display-buffer-use-some-window): Remove spurious
message included in 2021-01-11 "Support using auth-source for
NickServ passwords in ERC" (bug#45340#44).
Change calls from 'read-event' to 'read-key' in libraries expecting
mouse events. Do this only when 'xterm-mouse-mode' is enabled. That
way those libraries read decoded mouse events instead of the
underlying escape sequence. Add a parameter to 'read-key' that avoids
running any of the unbound fallbacks in 'read-key-sequence' so the
libraries can read mouse button-down events.
For backward compatibility purposes, the above logic is contained in a
new internal-only function: 'read--potential-mouse-event'.
* doc/lispref/commands.texi (Reading One Event): Document new
parameter to 'read-key'. Mention that non-character events on
terminals need 'read-key'.
* lisp/subr.el (read-key-full-map): Add new keymap used by 'read-key'.
(read-key): Add new parameter 'fallbacks-disabled' to prevent running
any of the unbound fallbacks normally run by 'read-key-sequence'.
(read--potential-mouse-event): Add new function that calls 'read-key'
or 'read-event' depending on if 'xterm-mouse-mode' is set.
* lisp/foldout.el (foldout-mouse-swallow-events):
* lisp/isearch.el (isearch-pre-command-hook):
* lisp/mouse-drag.el (mouse-drag-throw, mouse-drag-drag):
* lisp/mouse.el (mouse-drag-secondary):
* lisp/ruler-mode.el (ruler-mode-mouse-grab-any-column)
(ruler-mode-mouse-drag-any-column-iteration):
* lisp/strokes.el (strokes-read-stroke, strokes-read-complex-stroke):
* lisp/textmodes/artist.el (artist-mouse-draw-continously)
(artist-mouse-draw-poly, artist-mouse-draw-2points):
* lisp/vc/ediff-wind.el (ediff-get-window-by-clicking):
* lisp/wid-edit.el (widget-button--check-and-call-button)
(widget-button-click): Call 'read--potential-mouse-event' instead of
'read-event'.
* lisp/wid-edit.el (widget-key-sequence-read-event): Call 'read-key'
with 'fallbacks-disabled' set instead of 'read-event'. Unlike above
changes, this is unconditionally applied so it works for function
keys too. Apply 'local-function-key-map' instead of
'function-key-map' as that contains the full terminal translations.
* lisp/vc/ediff.el (ediff-windows): Use 'display-mouse-p' to check if
a mouse is available.
* src/lread.c (Fread_event): Recommend 'read-key' in docstring for
'read-event' for non-character events.
