Feature Request: Way to hide default help text

[GiuseppeIII]

Feature Request:
Option help text can be hidden with .hideHelp() and the default help text can be customized with .default() but there is currently no way to be able to hide just the default help text.

This would be helpful for some complex options where there is multiple parts to the default and so it is given in the standard help text.

I could see this being done either:

• as an option on hideHelp()
• by passing in undefined or null into the second argument on default()
• as its own method hideDefault()

A simple work-around might be to handle the default yourself if the option is not set rather than store it on the option.

You could override Help.optionDescription() to skip the default if option.defaultValueDescription is empty, but it is a page of code to copy and modify.

For built-in support through .default() could use either null or an empty string. null is more general but empty string is less likely to cause problems in code not allowing for new value of null.

Hmm I think I prefer null over empty-string as I have common situations where the default is an empty-string (though I guess one could also have situations where the default is null). This maybe would be considered a breaking change but it could make sense if you are trying to set a custom default description that you are allowed to control the entire default description and not just the part after default: ie {customDefaultDescription} over (default: ${customDefaultDescription})
