Have a catch-all for commands that don't exist. Provide useful information on potential commands user CAN use

[SpencerCDixon]

program
  .command('*')
  .action(function(env){
    console.log('Enter a Valid command');
    terminate(true);
});

Something like this

Seemed simple enough:

program
  .command('*')
  .action(function(cmd, env) {
    program.help()
  });

Except that this also intercepts the built-in redux help <cmd> such that the top level help is returned rather than the command specific help.

Which lead to this:

program
  .command('*')
  .action(function(cmd, env) {
    if (cmd === 'help') {
      program.emit('--help')
    } else {
      program.help();
    }
  });

Which works if you ask it nicely:

redux help generate

But barfs on missing command if you're lazy:

redux help

And barfs by running the command (?!) if you're over zealous:

redux help generate duck

Are you interested in a PR if I continue trying to refine this?

[SpencerCDixon]

Yeah if you get it working I'll definitely merge. Was probably going to start putting some more time into this project now that I'm settled into my new job/not ridiculously busy haha.

Appreciate you wanting to contribute!!

Cool. I'll see if I can do any better. I used yargs on my last project and it has similar quirks ;-)

Addressed by #110 implemented yargs and has been merged.
