I wondered if it might affect how "git checkout -" works. But that
feature looks for reflogs like "checkout: moving from X to Y" to know to
move back to X.  So we are fine here. Even though the HEAD reflog does
not show us going _to_ new-master, we would see it in a later entry as
"from new-master to Y". What we are missing is "rename from master to
new-master", but that entry does not matter. There is no "master" to
go back to anymore. :)
