Hello!
I've noticed that when offloading, --fallback sometimes fails to
actually fall back. Here is a shell transcript:

Interestingly no download was done on the second try, so apparently the

It looks like the offload hook starts before the actual download
(possibly because a substitute was advertised), and then fails when the
substitute 404s.
