Line wrap to reasonable length.

Instead of cheating, properly factor out reusable part from
cmd_checkout() into a set of libified routines, and make both
cmd_checkout() and cmd_switch() to call them

An approach like that would help "libify" things.  libifying is not
just reducing dependence of globals.

Calling main() from something else is not a libification.
