I was wondering what people would think of a smarter `save-buffer'
function. I was thinking that, if a file has been auto-saved since
the last time it was edited, then C-s (save-buffer) should maybe save
by renaming the auto-save file to the file itself. That would be
faster, right? (especially for our VM folders :-)
