This bug is a regression from Emacs 21.3.1.  When font-lock-add-keywords is
passed nil as the mode, fontification does not happen when font-lock-mode is
turned on.  Evaluate this form to reproduce the problem:

(progn
  (require 'font-lock)	
  (ignore-errors (kill-buffer "font-lock-bug-demo"))
  (switch-to-buffer "font-lock-bug-demo")

  (font-lock-add-keywords nil '(("hello" 0 font-lock-keyword-face t)))
  (turn-on-font-lock)

  (insert "The word 'hello' in this sentence should be fontified, but it isn't.\n\n")
  (insert (format "font-lock-mode == %s\n" font-lock-mode))
  (insert (format "font-lock-defaults == %s\n" font-lock-defaults))
  (insert (format "font-lock-defaults-alist == %s\n" font-lock-defaults-alist)))
