Instead of populating the second-level Bloom filter with every key referenced in every Git reference, consider only those which differ from what's referenced in the index. Incidentaly, unlike with its old behavior, staged modifications/deletion/... will now be detected by 'unused'. Credits to joeyh for the algorithm. :-)
