Default Value in CLI Showing Incorrectly

I have the specified custom symbol:

    "StyleCop": {
      "type": "parameter",
      "datatype": "bool",
      "description": "Adds and enforces StyleCop analysers. NOTE: You may need to sort using statements if you enable this due to limitations in the dotnet new templating engine.",
      "defaultValue": "false"
    },

However, when I check the help menu in the CLI using dotnet new api --help, I see that it looks like the default is true because it has a star beside it.

This was reported to me as a bug in https://github.com/Dotnet-Boxed/Templates/issues/758.

As was agreed with PM, I fixed the help message such that for normal behavior of the boolean switch no unnecessary/confusing information is shown. If and only if the “default if the option is without value” is unusual, the more verbose message will be shown.

These having different defaults feels wrong:

1. We may not use --parameter.
2. We may use --parameter without any value.

Let’s get Posix experts to weigh in on how common this is in the non-Windows world. From a Windows world, this made me cry.

I’d like to put this on the backlog for 5.0.200 so we have time to think through the behavior and how we want to express this.
