(setq outline-regexp (concat some-regexp... outline-regexp)) doesn't make
sense to me. Why do you append the old binding of the variable to your
new setting?
Also, you usage of `comment-start' is not correct. This regexp does not
necessarily match the complete comment start delimiter. For example, in
Emacs Lisp, `comment-start' is bound to ";", so your setting of
`outline-regexp' will not work for comments starting with more than one
semicolon. AFAICT, `comment-start' can even be nil for some modes.
HTH,
Michael.
