1//! `mkit switch` — git's modern branch-switch UX, a thin front-end over
2//! `mkit checkout`. `switch <branch>` switches to an existing branch;
3//! `switch -c <new> [<start>]` creates a branch and switches to it;
4//! `switch -C <new> [<start>]` creates-or-resets it. All the safety
5//! guards and output strings come from `checkout` unchanged.
