Nico, if you have time you may want to look into this. The result v4
pack from pack-objects on git.git for me is 35MB (one branch) while
packv4-create produces 30MB (v2 is 40MB). I don't know why there is
such a big difference in size. I compared. Ident dict is identical.
Tree dict is a bit different (some that have same hits are ordered
differently). Delta chains do not differ much. Many groups of entries
in the pack are displaced though. I guess I turned a wrong knob or
something in pack-objects in v4 code..
