Re: [PATCH v2 5/8] p5303: measure time to repack with keep

For showing the impact of the optimizations in patches 7 and 8, I think
doing a full repack with --honor-pack-keep is a better test. Because
then we're always doing a full traversal, and most of the work continues
to scale with the repo size (though obviously not the actual shuffling
of packed bytes around). That would get rid of the weird "no work to do"
case in the single-pack tests, too.

I meant to add: but I do like that we are timing --stdin-packs, too. We
may actually want to time both.

Another thing we _could_ do, if we have --honor-pack-keep perf tests, is
to shuffle patches 5, 6, and 7 towards the front of the series. They
should be able to show off the improvement even without the
--stdin-packs feature.
