(defun what-face (pos)
"Return the font-lock face information at the current point
Thanks to Miles Bader <miles-at-lsi.nec.co.jp> for this (gnus.emacs.help)"
(interactive "d")
(let ((face (or (get-char-property (point) 'read-face-name)
(get-char-property (point) 'face))))
(if face
(message "Face: %s" face)
(message "No face at %d" pos))))
