subcommands can't have a --version option

A primary command can take a --version option with the following code:

args.option('version', 'The version of the thing');

const flags = args.parse(process.argv, {
  version: false,
});

When I run my-command my-subcommand --help, I see

 -v, --version        The version of the thing

But when I run my-command my-subcommand --version=foo, flags.version is unpopulated.

I missed

If a function was passed through at this parameter, args will call it instead of running the binary related to that command. The function receives three arguments:

in the readme. Nice!

@jamesarosen this is also possible with args. You can put your code in the init function like this:

args.command('foo','foo subcommand', () => { 
// your code 
})

Then, the initfunction gets executed instead of running the binary for the subcommand.
