O que costuma-se supor
A leading space before a positional signature is ignored by Commander, so `program.arguments(' <name>')` is equivalent to `program.arguments('<name>')`.
O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.
Contrato
- In Commander 10, a leading-space argument signature is not ignored, so parsing `['node', 'app', 'only']` with `new Command().arguments(' <required> [optional]')` throws `commander.missingArgument` and does not accept a single positional argument.
- assert.equal(error.code, 'commander.missingArgument')
- assert.match(error.message, /missing required argument/)
