I dug up the actual JGit change, and it was indeed from 2014. So here's
a more complete series to handle that. There's a minor performance
mystery in the second patch, but I think it might be OK to proceed even
without solving it.
Conceptually these go on top of your patch, but they could be applied
separately.

[2/2]: pack-objects: default to writing bitmap hash-cache
