(defun diff-autosaved (&optional switches)
   "Diff this file with its auto-saved version or vice versa.
With prefix arg, prompt for diff switches."
   (interactive (list diff-switches))
   (let ((dir default-directory)
         (file (file-name-nondirectory (replace-regexp-in-string "#" "" (buffer-file-name))))
         bak ori)
     (if (string-match "^#" file)
	(setq bak file
	      ori (replace-regexp-in-string "#" "" file))
