Subject: 24.3.50; regression: font-lock broken since 2013-02-17

1. A user reported that Dired+ highlighting is completely broken now.  I
can confirm that this is so in this build from 2013-02-17, and that it
is not broken in a build from 2013-02-15.
 
If we need to dig further into this we can do so, but this regression
might be related to whatever causes the font-locking regression
described next, #2, and that is trivial to repro.
 
2. Font-locking of Emacs-Lisp files is broken too:
 
emacs -Q

(add-hook 'emacs-lisp-mode-hook 'turn-on-font-lock)
 
Then visit a buffer in Emacs-Lisp mode - no highlighting.
 
A call to `turn-on-font-lock' should never turn off highlighting.  If
already turned on, it should be a no-op.  This has always worked
previously, in Emacs versions going back at least to 20 and probably
(IIRC) to 18.
 
I looked for diffs between 2013-02-15 and -17 for font-lock.el and
font-lock-core.el, but I didn't see anything that stood out.
