The option method does not add the aliases to cmd.default object

Heya.

I know that in that cmd or "command object" we have both .alias and .default properties. But it isn't easy to merged them both in one single object.

For example

cli
  .command('foo', 'abc de')
  .option('-f, --format', 'some formatting', 'bar')
  .option('--fix', 'barry dazzle', true)

so they looks like

alias: { f: [ 'format' ] }
default: { fix: true, format: 'bar' }

So, it isn't possible to detect what default has what aliases. Would it be better the keys of alias object to be the name format in that case and its value to be its aliases? I believe that defining aliases in minimist (and probably mri) can accept both variants.

I want to merge them in one final object that is the same as "argv", same as the parsed result of mri/minimist, except the _.

Currently we should do something like that

Object.keys(cmd.alias).forEach((key) => {
  cmd.alias[key].forEach((alias) => {
    argv[key] = argv[alias];
  });
});
