Source Code
;; Defined in /usr/src/emacs/lisp/font-lock.el.gz
;; Originally these variable values were face names such as `bold' etc.
;; Now we create our own faces, but we keep these variables for compatibility
;; and they give users another mechanism for changing face appearance.
;; We now allow a FACENAME in `font-lock-keywords' to be any expression that
;; returns a face. So the easiest thing is to continue using these variables,
;; rather than sometimes evalling FACENAME and sometimes not. sm.
;; Note that in new code, in the vast majority of cases there is no
;; need to create variables that specify face names. Simply using
;; faces directly is enough. Font-lock is not a template to be
;; followed in this area.
