Actually, I think people loosened this over time and removal of
branch X is not rejected even if the range HEAD..X is not empty, as
long as X is marked to integrate with/build on something else with
branch.X.{remote,merge} and the range X@{upstream}..X is empty.
So the stress of "current branch" above you added is a bit of a
white lie.
