(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,
