I've implemented a first draft of this, complete with file-writing
capacity in the same macro: see the attached file and please comment.  (In
particular, is there a clean way to silence `save-buffer' or the
equivalent?)  I still don't quite have papers, but I am led to believe
that it will happen Real Soon Now; since this isn't going into this
release AFAIK, I hope that's not a problem.
