There is a bug in `turn-on-font-lock-if-desired' that causes it to miss
the first entry in font-lock-global modes in the case when the list does
not start with `not'.  A patch is enclosed below.

To make the bug manifest itself, put dired-mode first (and only once) on
the font-lock-global-modes list, and then switch to a new dired buffer.

Thanks; this is a regression against Emacs 22.  I've checked in your
patch into CVS.
