Thanks, this is a nice start. It's missing a few things IMHO:

  1. It actually counts commits, not all objects. I'm tempted to say
     this doesn't matter, as any eye candy is helpful. Except that the
     most common use of prune is as part of "git gc", in which case
     pack-objects will have just done the "counting objects" phase and
     come up with some number. If we count all objects, then our end
     number is the same (modulo any .keep packs, but at least it's
     probably in the same order of magnitude). That gives the user a
     better sense of completion time.

  2. Prune should learn --progress/--no-progress, isatty(2), etc. And
     git-gc should pass --no-progress when it's told to be quiet.

Patches for both in a moment.
