Hm. I don't really think that this progress meter adds anything right
now. It only shows either 0 or 1, so it basically only tells you when
you're done. And that is something that the user can tell without a
progress meter.

I think there needs to be a way to disable this. How about we add an
option `--[no-]references` to do so? I was briefly wondering whether we
also want to have `--only-references`, but if a user wants to do that
they can simply execute `git refs verify` directly.
