O que costuma-se supor
When both `--cache` and `--no-cache` are defined, omitting both options should leave `cache` as `true` because the negated form implies a true default.
O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.
Contrato
- With both `--cache` and `--no-cache`, parsing without either flag leaves `program.opts().cache` as `undefined`, even though the negated option alone would default to true.
- Without flags, `program.getOptionValueSource('cache')` is `undefined`, not `default`.
- Parsing `--cache` sets `program.opts().cache` to `true` and `program.getOptionValueSource('cache')` to `cli`.
- Parsing `--no-cache` sets `program.opts().cache` to `false` and `program.getOptionValueSource('cache')` to `cli`.
