Well... what needs to happen is everything between <script> and
</script> should be treated as text, but HTMLParser doesn't understand
that.

I *think* it would work fine to do:

  function hover(obj, text) {$(obj).append("&lt;span class=flag&gt; ("
+ text + ")&lt;/span&gt;");}

Which is actually something we could do automatically with a regex.
Unfortunately right now I can't reproduce, I put a test at the bottom
here: http://bitbucket.org/ianb/formencode/src/tip/tests/test_htmlfill.py
-- but it passes.
