Sorry if this is already known - I did look through the list down through last August - only the "for" in "format" is highlighted in a different colour in slime-mode.

This sounds strange. SLIME doesn't do much highlighting. defun and such are highlighted by lisp-mode and not by slime-mode. SLIME does some special things like #+foo if foo is not a feature, but that seems to be unrelated to your problem. Maybe you have some strange syntax highlighting code your lisp-mode-hook?
