So with 1.3.0.g56c1 "git repack -a -d -f" did worse:

  Total 46391, written 46391 (delta 6649), reused 39742 (delta 0)
  129M pack-7f766f5af5547554bacb28c0294bd562589dc5e7.pack

I just tried -f on v1.2.3 and it did slightly better then before:

  Total 46391, written 46391 (delta 6847), reused 38012 (delta 0)
   59M pack-7f766f5af5547554bacb28c0294bd562589dc5e7.pack
