Re: [BUG] No fontification when font-lock-add-keywords is passed nil as the mode

[Richard Stallman]

      Eval this form to see the below
    backtrace:

    (progn
      (require 'font-lock)
      (defun my-dired-mode-hook ()
        (font-lock-add-keywords nil '(("^  d" 2 'highlight nil)))
        (turn-on-font-lock))
      (add-hook 'dired-mode-hook 'my-dired-mode-hook)
      (dired "/"))

This should fix the bug.
