That reasoning sounds sensible. Especially given the discussion of
"checkpoint" and "progress" we can see in "git fast-import --help"
documentation. E.g.
Placing a progress command immediately after a checkpoint will
inform the reader when the checkpoint has been completed and it
can safely access the refs that fast-import updated.
would not be true without this change, I suspect.
Can we also add a new test or two that protect this from future
breakages?
Thanks.
