That sounds like a workable approach, modulo that the details of the
"signature file with a certain name" part needs to be worked out.

We should make sure that we clearly document that "--add-file=" and
friends add their material after the contents that come from the
tree-ish, and make sure that the program does so and will stay doing
so.  Otherwise users cannot easily create an archive that follows
the above rule.

Thanks.
