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? ;-)
