Problem with describe-function

[Nick Roberts]

A face (something defined with defface) seems to be neither a function
or a variable. So if I do `C-h f next-error', it (correctly) says

next-error is an interactive compiled Lisp function in `simple'.
It is bound to C-x `...

However clicking mouse-2 on `simple' takes me to:

(defface next-error
  '((t (:inherit region)))
  "Face used to highlight next error locus."
  :group 'next-error
  :version "21.4")
