It doesn't need to be nearly as restricted as :first-line, since
it's tree-like.  It's much more like :before and :after.

(For more on the distinctions, see the comment I wrote at
http://hg.mozilla.org/mozilla-central/file/4cabe72ad940/layout/style/nsCSSPseudoElements.h#l50
, and note that it mentions a third intermediate category, in which
some proposed XForms pseudo-elements, and perhaps some future
pseudo-elements, would fit.)
