Describe the bug
When using Commands can't use Option with short name with more than 1 letter.

To Reproduce
Steps to reproduce the behavior:
1.Create main class:

    [Subcommand(typeof(SCmd1))]
    [Command(Name = "Cmd")]
    class Program
    {
        public static int Main(string[] args)
            => CommandLineApplication.Execute<Program>(args);


        public void OnExecute(CommandLineApplication app)
        {
            app.ShowHelp();
        }
    }

2. Create command class:

    [Command("SubCommand1", "SC1")]
    class SCmd1
    {
        [Option(Description = "first option", ShortName = "o1", LongName = "option-1")]
        public string Option1{ get; } = null;

        public void OnExecute(CommandLineApplication app)
        {
            ...
        }

3. Run command Program SC1 -o1 whatever
4. Get error Unrecognized option '-o'

Expected behavior
I would expect to recognize the option "o1" and to set the property "Option1" with the value "whatever".

Can confirm this is a bug. Give this pre-release build a try: https://myget.org/feed/natemcmaster/package/nuget/McMaster.Extensions.CommandLineUtils/2.3.4-build.22

I see 2.3.3 as the last version in my VisualStudio project. Could you create a pre-release so that I can test this change?

Thanks.

[natemcmaster]

I already created a prerelease. Follow the link I shared in the previous comment.

I did not realize it was on your own feed.
It works as expected now.

Thanks for your help Nate and keep up with the good work!

[natemcmaster]

Thanks for confirming. I'll push an update to nuget.org in a week or so. I'm waiting to see if anything else is needed in the next patch.
