"When anybody wants the contents of deadbeef, give the contents of
its replacement" is what the replace (graft, too) is.

> git branch didn't do that; it put deadbeef into refs/heads/foobar.

Yes, but refs/heads/foobar having deadbeef does not have a problem,
as long as you get the contents of the replacement object when you
ask for the contents of deadbeef (or "the object referred to by
the refs/heads/foobar ref").
