  ;; This is used to override the value on a `*-font-lock-keywords'
  ;; variable only if it's nil or has the same value as one of the
  ;; `*-font-lock-keywords-*' variables.  Older font-lock packages
  ;; define a default value for `*-font-lock-keywords' which we want
  ;; to override, but we should otoh avoid clobbering a user setting.
  ;; This heuristic for that isn't perfect, but I can't think of any
  ;; better. /mast
