Revno 111881 fixed the obvious problem with whitespace-mode, here's a
less obvious one.
This seems to be localized to sgml-mode and its derivatives so far:
js-mode, ruby-mode, etc are not affected.
1. (add-hook 'sgml-mode-hook 'whitespace-mode)
2. Open a file in sgml-mode or html-mode, or create a buffer and turn
either mode manually. whitespace-mode will be enabled.
3. M-x whitespace-mode => it's disabled, font-lock is gone, the value of
font-lock-keywords is (t nil).
On the surface, the reason for this is that when whitespace-mode is being
turned on in the hook, font-lock-keywords is still nil, and so nil is
saved in whitespace-font-lock-keywords.
