I'm not quite sure about this anymore... It seems to me that
css-expand-length is supposed to return the number of character cells
needed to fill the given length (at least w3-display-handle-list-type
in w3-display.el assumes that; see the format string involving
"margin"), not the length in points; the previous version did the
former, but apparently (see <URL:http://article.gmane.org/gmane.emacs.
devel/67607>) this makes lists annoyingly wide.  What problem was this
change supposed to solve?
