    Maybe something like this would be a start?

    (defmacro set-face (face spec &optional doc &rest args)
      `(if (facep ',face)
	   (face-spec-set ',face ,spec)
	 (defface ,face ,spec ,(or doc "REPLACE ME") ,@args)))

This seems like an incoherent combination of two different constructs,
like a conditional choice between set and setq.  I don't think it is
a good idea.

We might want to make `set-face' an alias for `face-spec-set'.
