Since you haven't provided any hard data, I'll give you a sample solution to
another problem:

   (set (make-local-variable 'comment-start-skip)
        "#+[ \t]*\\|\\(uglyprefix +\\)--+[ \t]*")

Now maybe you problem can't be solved in the same way, of course.
The group-1 convention doesn't cover all cases.
