v2.0.0-beta5.25306.1

I have some default values that can be sourced from environment variables if they're present.

For example,

 var passwordOption = new Option<string?>("--password". "-p", "/p") { Description = "The password to use.", DefaultValueFactory = defaultValue => { if (string.IsNullOrWhiteSpace(Environment.GetEnvironmentVariable("_Password"))) { return null; } return Environment.GetEnvironmentVariable("_Password"); } };

Currently the help text would display

-p, --password The password to use. [] 

It would, to my mind, be cleaner if, when the DefaultValueFactory returns null that nothing is displayed as the default, because in this case there is no default.

e.g.

-p, --password The password to use.
