Robin,

That sounds like a good idea. How would you expect it to act? We don't
have any other interactive features, so asking for confirmation would
be a departure from our usual way of doing things. We could also just
append to the filename if it exists, or copy the old one to X.orig, or
something.

For future reference, I usually avoid this problem by including %T in
my output filename to include the timestamp, so unless I do two scans
within a second of each other, there's no clobbering.
