Thanks for the suggestion!

Even then, I don't think this works in CC-mode, or in any language that has 
two-character comment markers: it works in Lisp because the comment marker is a 
single semicolon. But in OCaml, for example, (* is a comment marker and 
syntax-ppss doesn't see (<point>* as a comment. This matches your explanation, 
but I don't think the solution applies to that case.
