Add a predicate, color-dark-p, for deciding whether a colour is more
readable with black or white as contrast. It has experimentally been
shown to be more accurate and robust than the various methods
currently employed.
The new predicate compares the relative luminance of the colour to an
empirically determined cut-off value, and it seems to get it right in
almost all cases, with no value leading to outright bad results.
* lisp/faces.el (readable-foreground-color): Use color-dark-p.
(color-dark-p): New function.
* lisp/facemenu.el (list-colors-print): Use readable-foreground-color,
improving readability of list-colors-display.
* lisp/textmodes/css-mode.el (css--contrasty-color): Remove.
(css--fontify-region): Use readable-foreground-color.
* lisp/textmodes/css-mode.el (css-nmchar-re): Allow underscores in
variable names (and in identifiers in general).
* test/manual/indent/css-mode.css: Add some examples of variable names
with underscores in them.
* test/manual/indent/less-css-mode.less: Add some examples of variable
names with underscores in them.
* test/manual/indent/scss-mode.scss: Add some examples of variable
names with underscores in them.
* lisp/textmodes/css-mode.el (css-mode-map): Remap `complete-symbol'
to `completion-at-point'.
(css-mode): Update docstring to produce the right key binding.

another way that the syntax is that of character alternatives.
(picture-set-tab-stops, picture-tab-search): Don’t attempt
to regexp-quote picture-tab-chars.
(picture-tab-search): Quote \ in picture-tab-chars for
skip-chars-backwards, which treats \ differently than
regexp character alternatives do.

This fixes highlighting for class names that contain --, for example:
.foo--bar {
display: none;
}
* lisp/textmodes/css-mode.el (css--font-lock-keywords): Make regular
expression stricter.
* lisp/textmodes/css-mode.el (css--colon-inside-selector-p): Fix
indentation of multi-line CSS selectors that include both a
pseudo-class and parenthesis.
* test/manual/indent/css-mode.css: Add test for the above change.
* lisp/textmodes/css-mode.el (css-lookup-symbol): Keep the eww buffer
current when looking up CSS documentation on MDN. This fixes a bug
where the eww buffer's content sometimes get mangled when switching
buffers mid-render.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
* lisp/textmodes/css-mode.el (css-smie-rules): Provide better support
for indentation of detached rulesets passed to Less mixins.
* test/manual/indent/less-css-mode.less: New file.
* lisp/textmodes/css-mode.el (css-property): Inherit from
`font-lock-keyword-face' instead of `font-lock-variable-name-face' to
distinguish CSS properties from variables.
* lisp/textmodes/css-mode.el (css--complete-property-value): Be less
eager by looking for a colon after the property which values are being
completed for.
* test/lisp/textmodes/css-mode-tests.el (css-test-complete-property):
Add a test case ensuring that properties that are prefixes of other
properties don't hinder further completion.
* lisp/textmodes/css-mode.el (css--font-lock-keywords): Fix
highlighting of selectors that contain double hyphens. They would be
mistaken for a variable.
* lisp/textmodes/css-mode.el (css-smie-rules): Indent after property
immediately followed by a newline.
* test/manual/indent/css-mode.css: Add test for the change above.
* test/manual/indent/scss-mode.scss: Ditto.
