    Is there a reason why font-lock-face should be preserved on copying?

Perhaps it should be preserved when copying into a non-font-lock
buffer, but discarded when copying into a buffer with font-lock

On the topic of yanking fontified text into non-font-lock buffers,
I became annoyed when any following keyed text would inherit those
properties, so I put this in my .emacs file:

(defadvice yank (after rear-nonsticky activate)
  "Make all yanked text properties rear-nonsticky, unless Font Lock is on."
  (unless font-lock-mode
    (put-text-property (region-beginning) (region-end) 'rear-nonsticky t)))
