I imagine lars kept the logic from the original 'mm.el' that converts
wildcard matches like that to regular expressions.

Something along the lines of:

	(setq minor
	      (cond
	       ((= ?* (or (char-after save-pos) 0)) ".*")
	       ((= (point) save-pos) ".*")
	       (t (buffer-substring save-pos (point)))))

I guess there should be a regexp-quote in there for the last case.  I have
no idea where this code lives in the currently redesigned 'mm-*'
libraries.  Lars?
