Yes, I think that warning about the auto-saved file when you try to edit
the new file has possibilities...  I'm wondering whether there would be
any adverse effects somehow.  Emacs has a number of things that warn
about editing files -- that it's changed on disk, or that another Emacs
process has the file locked, and now checking for auto-saved files in
the same area would perhaps add unforeseen complications.

But perhaps we should just try and see what it feels like in practice.

We do have a very primitive sort of message priority -- i.e., we have
some things that are so bad that we pop up the *Warnings* buffer.  But I
think that's too intrusive for auto-saved files.
