Ok, I see this specifically a problem with GNU option collapsing, overloading help and not returning an appropriate error for invalid usage when invalid options are passed to '-h'. Frankly, if I wanted to collapse lots of options, I would either make another option simply for that (or option concatenation option like '-c') or introduce sub-commands. Better design and more human-memorizable. But thanks for detailed response. Upvoted for explanation. :).
