Selectors level 4 adds support for wildcards (*) in the :lang() selector, with reference to RFC4647 language matching. We should probably implement this, and **at the same time** add support for string arguments to :lang(). http://dev.w3.org/csswg/selectors/#the-lang-pseudo https://lists.w3.org/Archives/Public/www-style/2015Jan/0269.html (minutes of meeting, not yet reflected in draft, where WG agreed that argument should either be ident or quoted string)

This is a Selectors-4 enhancement to the spec for the :lang() pseudo-class.
It seems Safari has been shipping this behavior for some time.

This is the other extension to the :lang() pseudo-class in Selectors-4.
(Also supported in Safari.)
Depends on D174999

This allows to clean-up the previous patches by using a single ThinVec
(which stores length / capacity along with the allocation).
