options with embedded whitespace.
* lisp/files.el (insert-directory): Use split-string-and-unquote
to support dired-listing-switches that specify command-line
options with embedded spaces. (Bug#25485)
Make the existing if-let and when-let aliases.
* lisp/emacs-lisp/subr-x.el (if-let*, when-let*): New macros. Rewrite
docstrings, incorporating that from let* and the existing if-let.
(if-let, when-let, and-let*): Alias them.

* lisp/cus-start.el: Make it customizable.
* etc/NEWS: Mention it.
* doc/emacs/display.texi (Auto Scrolling):
* doc/lispref/windows.texi (Textual Scrolling): Document it.
* src/window.c (window_scroll_pixel_based): Use it instead of hardcoding
division by 4 (Bug #5718).
* lisp/replace.el (list-matching-lines-current-line-face)
(list-matching-lines-jump-to-current-line): New user options.
(occur--orig-line, occur--orig-line-str): New variables.
(occur, occur-engine): Use them.
(occur--final-pos): New variable.
(occur-1): Use it.
(occur-engine): Idem.
Show the current line with 'list-matching-lines-current-line-face'.
Set point on the first matching line after the current one.
* etc/NEWS: Add entry for the new option.
Another step in the long history of list-buffers-directory. A thread
branch discussing the meaning/use of the variable starts here
https://lists.gnu.org/archive/html/emacs-devel/2009-09/msg00684.html
Also see (info "(elisp) Buffer File Name").
* lisp/buff-menu.el: Relocate special case code into info.el. Nix
Info-* defvars.
(Buffer-menu--pretty-file-name): Remove special case. Use
bound-and-true-p.
(Buffer-menu-info-node-description): Remove.
* lisp/ibuffer.el (ibuffer-buffer-file-name): Treat
list-buffers-directory as a string.
* lisp/info.el (Info-node-description): New function.
(Info-select-node): Use it.
With the previous defaults, doing image-dired on a directory with an
animated foo.gif would cause creation of foo.thumb-N.gif for each of
N frames in foo.gif. By default image-dired looks for foo.thumb.gif, so
there additionally is no usable thumbnail after all the needless effort.
image-dired never handled animation, regardless.
* lisp/image-dired.el: Mention limitation.
(image-dired-cmd-create-thumbnail-options):
(image-dired-cmd-create-temp-image-options):
(image-dired-cmd-create-standard-thumbnail-options): Append [0] to
filename to indicate only converting the 0th frame.
(image-dired-display-image-mode): Don't show a cursor.
This fixes bug #24431. The key change of this bug fix is correctly analyzing
nested brace lists when the opening element stands on the same line as both
its introductory brace and an enclosing parameter list parenthesis.
* list/progmodes/cc-align.el (c-lineup-under-anchor): New line-up function.
* list/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): Accept the
presence of exactly an identifier between an open parenthesis and an open
brace as evidence of the brace starting a brace list.
(c-looking-at-statement-block): New function, extracted from
c-looking-at-inexpr-block. Enhance it to analyze inner blocks recursively
when needed.
(c-looking-at-inexpr-block): Extract new function (see above) and call it.
(c-add-stmt-syntax): Enhance, with new &optional parameter, to supply the
prime syntactic symbol with a fixed anchor point. When this is used, restrict
all added syntactic symbols to those having an anchor point on the same line.
Add, in addition to the current additional symbols, c-brace-list-entry when
needed; use c-looking-at-statement-block to determine the latter.
(c-guess-basic-syntax, CASE 9D): Use c-add-stmt-syntax rather than just
c-add-syntax, to assemble the syntactic context of a 'brace-list-entry, thus
getting, possibly, several accompanying syntactic entries.
* lisp/progmodes/cc-styles.el (c-style-alist, "gnu" style): New entry for
'brace-list-intro, namely c-lineup-arglist-intro-after-paren.
* lisp/progmodes/cc-vars.el (c-offsets-alist): Change the factory default
offset for 'brace-list-entry from 0 to c-lineup-under-anchor.
* doc/misc/cc-mode.texi (Syntactic Symbols): Amend the definition of
brace-list-intro.
(Brace List Symbols): Amend the example to show the new analysis of brace
lists when the first element comes on the same line as the opening brace.
(Misc Line-Up): Document the new line-up function c-lineup-under-anchor.
This reverts commit d1c9310090.
Not all the cases where we had string-as-unibyte were characters,
so this needs to be considered more thoroughly before being redone.
* lisp/gnus/gnus-art.el (gnus-article-mode-syntax-table): Make
M-. in article buffers work for `foo' strings, and still allow
C-s C-w to yank ' to the search ring (bug#22248).
lisp/comint.el (comint-get-old-input-default): Modify behavior to follow
docstring: if `comint-use-prompt-regexp' is nil, then return the CURRENT LINE,
if point is on an output field.
* etc/NEWS: Mention new feature.
* lisp/textmodes/css-mode.el (css-mode-map): New defvar.
(css--mdn-lookup-history): New defvar.
(css-lookup-url-format): New defcustom.

defuns.
* test/lisp/textmodes/css-mode-tests.el (css-mdn-symbol-guessing): New
test.
* lisp/emulation/edt-mapper.el (edt-mapper): New function,
containing code previously at top-level.
* lisp/emulation/edt.el (edt-load-keys): After loading edt-mapper,
run edt-mapper function.

Refer to the language consistently as JavaScript.
* lisp/net/eww.el (eww-download): Check accessibility of
eww-download-directory to prevent starting a download that will fail
to write.
* src/fileio.c (Faccess_file): Clarify the use of string argument in
the docstring.
* lisp/gnus/message.el (message-send): If the hook modifies
the message (mml tags or headers), we should check bcc on the
final message, not on the original.
* lisp/htmlfontify.el (hfy-which-etags): Don't call a shell for
detecting the etags version (Bug#25468).
* test/lisp/htmlfontify-tests.el (htmlfontify-bug25468): Add unit
test.
