[patch] 21.3 find-dired.el - Add 'g' key to repeat last find command

[Jari+mail.emacs]

As with dired 'g', the results of find-dired can now be repeated. With log
files and IMAP mail directories, this feature is quite useful.

2005-01-21 Fri  Jari  <jari dot aalto A T cante dot net>

        * find-dired.el (find-dired-revert): New function.
        (find-dir): New variable.
        (find-dired): Added local `revert-buffer-function' and
        restored key 'g' to rerun last find command.
