Never noticed that before. IMHO, it's ugly and broken in a number of
browser which don't handle the "content" attribute very well (firefox
on solaris and IE 8 are bad for different reasons, looks ok on Chrome)
and should be removed entirely instead of trying to keep up w/
babel. I can't say why the list is limited to the specific set of
languages, but since this is part of a defconst for the default inline
styles, it pretty much needs to be hard-coded.

Note that you can easily add other languages via `html-head-extra'.

I've been thinking about how to cleanup the whole inine css/javascript
thing since it makes for bloated (but standalone) html documents, and
in the case of inline css, is broken in batch export due to the use of
htmlize (see `org-html-html-htmlize-output-type').
