-B <new-branch>::
With `add`, create a new branch named `<new-branch>` starting at
`<branch>`, and check out `<new-branch>` into the new worktree.
+ If `<branch>` is omitted, it defaults to HEAD.
By default, `-b` refuses to create a new branch if it already
exists. `-B` overrides this safeguard, resetting `<new-branch>` to
`<branch>`.
