Hello,

Indeed.  Plus, I want to look at the font-lock-face property.

There's no difficulty.  Eli, did you ever read the code snip I had
included?  Here it is again:

(cl-some
 (lambda (face) (not (memq (face-foreground face nil t)
		      `(nil
			,(face-attribute 'default :foreground)
			"unspecified-fg" "unspecified-bg"))))
 (cl-mapcan (lambda (face-or-list) (if (facep face-or-list)
				  (list face-or-list)
				face-or-list))
	    (list
	     (get-text-property (point) 'face)
	     (get-text-property (point) 'font-lock-face))))

I think what you mean, and what I do in the code, are quite the same
(except for the predicate maybe).  I appreciate your help, but please
tell me if the snipped is ok or if you mean something else, and if so,
what.  I've just the feeling that we to talk at cross-purposes.


Thanks,

Michael.
