One of git-worktree's roles is to populate the new worktree, much like
git-checkout, and thus, for convenience, ought to support several of the
same shortcuts. Toward this goal, add -b/-B options to create a new
branch and check it out in the new worktree.

For brevity, I intentionally mentioned only -b in the synopsis, and
omitted -B.

+-b new-branch::
+-B new-branch::
+ With `add`, create a new branch named `new-branch` starting at
+ `branch`, and check out `new-branch` into the new worktree.
+ By default, `-b` refuses to create a new branch if it already

With `add`, detach HEAD in the new worktree. See DETACHED HEAD in
