I was wrong, it actually does fix a problem, just not the one we thought
it would fix. When all packfiles are non-local, git-multi-pack-index(1)
would end up returning an error because it cannot find any of them. So
by skipping over these non-local packfiles early on we avoid spawning
it altogether and thus avoid the error.
