Junio: Just a reminder that next is still broken with this, and I see
e.g. the Debian "experimental" has the bug but not the fix at this
point.
I'm just reverting jk/pack-delta-reuse-with-bitmap out of next when
building my own package of git, but I think this really should be fixed
in that branch, either by merging the fix down or reverting the original
series out of next, I think just merging the fix down makes sense, but
have no strong opinion on it.
