Title: Mark command parameter required if there is no fallback

This change results in:

- The "command" parameter being shown as rather than
[optional] when there is no fallback set with .nocommand()

- It being an error (thus showing help) if no command is passed when
one is expected, and there is no fallback set with .nocommand()
