problem with save-excursion

[Mike Krell]

Hello,

I've written a little elisp function to run the current buffer 
through perl (or any other command).  However, the current region is 
lost as a result of running the code, even though I'm using save-
excursion.  Can anyone help with this?

   Thanks,
   Mike

defun perl-replace-buffer ()
  "Apply perl command to buffer"
  (interactive)
  (save-excursion
    (mark-whole-buffer)
    (let ((start (region-beginning))
          (end   (region-end)))
      (shell-command-on-region start end 
        (read-from-minibuffer "Command: " '("perl -pe \"\"" . 11 ))
          t
          t
          )
      )
    )
  )
