That looks pretty standard to me. But more important, it works
great!
I take it the temporary file~ is what you used for testing?
Anyway, it boiled down to this - awesome stuff:
(defun su-edit ()
"Edit the current buffer file as superuser."
(interactive)
(let ((window-start (window-start))
(point (point)) )
(find-alternate-file (format "/sudo::%s" (buffer-file-name)))
(goto-char point)
(set-window-start nil window-start) )) ; nil - selected window
