before?
See diff-buffer-with-file.
Yes, that was the idea. I was going to hook a function into
before-save-hook which does pipe diff -u $1 $2 | diffstat and show the
result in some kind of minibuffer. Not sure how to set $1 and $2 (in
fact, I've never written any elisp at all). I don't suppose anyone could
whip up the code in a moment or two? ;-)
