If I comment text that starts at column 0 (a top-level sexp) like this

;;; (defun foo ()
;;;   (do-this)
;;;   (do-that)
;;;   (do-another-thing))

with comment-style set to indent-or-triple it results in the first line
being matched by outline-regexp.  With comment-style set to indent,
which inserts only two semicolons, this is not the case.  I don't know
if it's good to have commented top-level sexps as outline regexps.

comment-dwim for text that doesn't start in line 0 seems to always
produce comments that are not matched by outline-regexp, because the ;;;
is followed by more than one space.
