Allow exit when no option is matched

[tocttou]

vorpal
  .catch('[catch...]')
  .option('-p', '`-p <PID>`')
  .action((args, cb) => {
    if (args.options.p) {
      console.log('yo');
    } else {
      console.log(':(');
    }
  })

This does not drop out of the shell if the supplied option is incorrect.
