Verbatim values are parsed as options (when they shouldn't be)

[cdmihai]

Given an options class with an option of type string:

    class Options
    {
        [Option('c', "command", HelpText = "command")]
        public string Command { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            var result = Parser.Default.ParseArguments<Options>(args);

            result
                .WithParsed<Options>(
                    o =>
                    {
                        Console.WriteLine($"{o.Command}");
                    })
                .WithNotParsed(
                    e =>
                    {
                        Environment.Exit(1);
                    });
        }
    }

I would expect multi word values surrounded by quotes to be treated verbatim as a value for the string option.

Instead, CommandLineParser may end up parsing the verbatim string when it shouldn't:
