Guys, I've got a problem. my mail takes up about 1/2 as much space as
is left onthis disk partition. Therefore, when RMAIL does a save, it's
50-50 whether the disk'll fill or not. The obvious answer is to stop
rmail making a backup file - it makes enough security copies as it is.
So, what's the neatest way to stop the file .rmail being backed up? I
know that to disable backups, you set the variable make-backup-files
to nil, but how do you make sure it's reset when you've finished? I've
got that to set the variable you make rmail-mode-hook equal to
(setq make-backup-files nil), but even that looks like a hack, and I
don't know of an rmail-exit-hook or whatever. Logic should suggest
that you can control backup behaviour for each buffer, but I can't
find out how to do that.

	Of course, the easy answer's to go over to vm, but vm seems
not to want to give me any headers when it displays a message... when
I've got the behaviour nailed down I'll post a report on it.
