"git prune" relies on "git rev-list --all" to list all reachable,
non-prunable commits. In the presence of per-worktree refs such as HEAD
this becomes more complicated.
Add a test that makes sure that per-worktree refs from other worktrees
are not omitted.
This is currently broken, possibly resulting in data loss.
