It's not *quite* the same topic, but a related WIP patch that got
dropped (and it would be great if someone looking at this area could
pick it up) is
https://public-inbox.org/git/20180902085503.GA25391@sigill.intra.peff.net/

I think it's also worth looking into making the progress code able to
emit stuff like:

    Counting / Compressing / Writing objects A% (X_1/Y_2) B% (X_2/Y_2) C% (X_3/Y_3)

That would allow for splitting up some of these cases where our progress
bars are overly verbose across multiple lines without losing info by
completely erasing the line, and would also support other cases where
sometimes we do this stuff concurrently. See e.g. my recent commit-graph
progress patches for something that would benefit from this type of
thing.

It would need a patch to the progress code to make it able to juggle N
number of progress bars with some format to stitch them all together.
