Right.

I am leaning towards the former (though we may also end up doing the
latter).

Here is an initial attempt.  It turns out that write_archive() must
be callable outside a repository to respond to "git archive --list",
which happens in parse_archive_args(), and the "have-repository?"
check cannot be moved before that to the caller.

No tests yet.  Help appreciated ;-)
