Fair point. Now I'm thinking harder I can't think of any other reason
myself other than -?
Maybe I could make it check for -? With a property?  Args.QuestionMarkIsHelp

Another point: I didn't notice that you added a 'Args.HelpText()' method

To begin with the Args.HelpText() method did not have an option to print it
just returned the text for printing with 'Print Args HelpText()'
I guess I thought printing it would be most used so I added the option.
Clearly I am not as sane as you 🤪
I think it has uses. The arg descriptions could contain Subst() tokens and
be customised at runtime using the text.

Am adding a boolean property to the class due to what other Bruce said
called Args.ExpandShortNames. if true It stops an arg like -ab being seen
as -a and -b and sees it as -ab.
