Subject: hpricot 0.4.76 chokes on empty comment.

Hpricot's choking on some pages complaining about nil
in Comment#parse.  I can't remember the HTML page that
was parsing it; but this patch fixes the problem for me.

Why?  If you're around, should something like this be checked
in the main project?
