(thanks to Nikolaj Schumacher & Tassilo Horn) but in summary, i think the way it is is rather odd. It is rather =20 strange and difficult to understand unless the user has expert elisp =20 knowledge, and it is somewhat not typical with how most other major =20 mode for languages syntax color the lang's keywords. (emacs-lisp-mode doesn't seem to support customize-group and font-=20 lock-maximum-decoration) i think the current behavior is severe enough to be considered a bug. This is emacs 22.x.
