Thank you.  That was my impression, too, but I wasn't 100% sure.  Given 
this, my updated suggestion is:

(defun font-lock-update (&optional arg)
  (interactive "P")
  (save-mark-and-excursion
    (if (not arg)
        (font-lock-fontify-region (point-min) (point-max))
      (font-lock-unfontify-region (point-min) (point-max))
      (font-lock-mode 'toggle))))
(global-set-key (kbd "C-x x f") 'font-lock-update)
