👍 for the new branch command.  Until now, I avoided ‘vc-create-tag’
to not make a mistake that will create a tag instead of the branch.

Shouldn't tag commands be moved to another prefix key ‘C-x v t’?
But I don't know how often tag commands are used.

A prompt for START-POINT would be fine with completion on branch names,
and saying what the default value will be used when exiting with RET.
