Allow long arguments to be optional

Feature Request: Allow long arguments to be optional.

Long arguments should be optional, as is the case for short arguments. A check should be done that at least one of the short/long argument is non-empty.

In the README is explicitly mentioned that long arguments must be specified and non-empty. Is there a reason for this other than a limitation by current implementation? Would a PR to implement this FR be accepted?

Thanks for raising this issue. Sure, if the PR is sent to implement this it will be reviewed/accepted.

hi there

I saw this issue and decided to give it a shot. I've just opened a PR #124 that updates the validation logic to allow short-only arguments I also added some tests to cover this case, let me know what you think!
