Incorrect comment (?) in ffap.el

[Drew Adams]

Is this comment in ffap.el correct?

;;; Compatibility:
;;
;; This version of ffap supports Emacs 20 only, see the ftp site
;; for a more general version.  The following functions are necessary
;; "leftovers" from the more general version.

I'm behind a firewall, so I cannot get to the ftp site to check the
differences from the version that comes with Emacs. But it seems
incorrect that Emacs 22 would include a file that works only with
Emacs 20. Also, the Emacs 22 version is definitely different from both
the Emacs 20 version and the Emacs 21 version. So, I suspect that the
comment is incorrect.
