Yes, pack-objects respects pack.packsizelimit when creating local packs,
but incoming packs from the network (which are processed by index-pack)
are not split.

This should be fixed in git. Unfortunately, I don't know that it is as
trivial as just splitting the incoming stream; we would also have to
make sure that there were no cross-pack deltas in the result.
