Well, according to the log it worked for some branches for Thomas, just
not for all of them. I'm not surprised your test succeeds. In Thomas'
case it seems that repack is missing some dependencies, but it doesn't
even have an --all option or such.
Thomas: In addition to your git version, it would be good to know
whether you use any of
- grafts
- replaced objects
- multiple roots (branches without common commits)
- alternate chains (source repo borrowing objects from a third repo)
