Yeah, what I was confused by was testing this with "git gc", and until
my recent commit graph progress patches + this (which I wasn't testing
against) the progress output was all from pack-objects, which checks the
--progress option, and then proceeds to ignore all of that and just
check isatty().

Thanks.
