Is that the syntax table returned by (syntax-table) and set by (set-syntax-table TABLE)? The doc string does not mention this. I thought that perhaps the comment delimiters where involved. The syntax tables as above seems to be able to take care of C style comments (max 2 chars in delimeters), but it can not handle html comments AFAICS. I guess then parse-partial-sexp can not return info about html comments, right? Can syntax-pps do that?

Thanks.
