Brandon CaseyThe -A option calls pack-objects with the --unpack-unreachable option so that the unreachable objects in local packs are left in the local object store loose. But if the -d option to repack was _not_ used, then these unpacked loose objects are redundant and unnecessary.
Update tests in t7701.

Here is another patch for bc/maint-keep-pack that seems to make sense. I can't think of a reason why porcelain repack should unpack the unreferenced objects if it's not going to delete the packs they were in.
