If piping from mutt, a set of files. If saving to an mbox
from mutt and piping from command line, one mbox.
So both.

What I had in mind is that I might have multiple patchsets under test
on an unstable branch X.
Now I decide to copy one patchset to the stable branch.

With a single patch I would just cherry-pick.

Yes, except cherry-pick has the -x flag to track where did
I get the patch from. And I would like this info recorded
for the cover as well. Maybe format can export that info.
In fact this might be a handy flag for format-patch too:

ability to add (cherry-picked from commit XYZ "subject")

automatically.
