Shon config parsing doesn't know what to do with -?

[tustin2121]

The configuration parsing does not seem to know what to do with a non-alphanumeric option, such as -? as a short form of --help. It doesn't look like the definition for help is parsed at all in the following SSCCE:

var Command = require("shon");

var cmd = new Command("serve",{
    ip: "[--ip <ipaddr>] IP Address to serve from.",
    port: "[-p|--port <port>] :number The Port to serve from.",
    help: "[-?|-h|--help]*",
});

var config = cmd.exec();

console.log("RES", config);

if (config === "help") {
    console.log("Hello world");
    cmd._logUsage();
    process.exit(0);
    return;
}

Results:

>node server.js -?
usage: serve
  [--ip <ipaddr>] IP Address to serve from.
  [-p|--port <port>] :number The Port to serve from.
  [-?|-h|--help]*

Unexpected flag: "-?"
serve -?
      ^

>node server.js -h
usage: serve
  [--ip <ipaddr>] IP Address to serve from.
  [-p|--port <port>] :number The Port to serve from.
  [-?|-h|--help]*

Unexpected flag: "-h"
serve -h
      ^

Ah, indeed. Might be able to address that.
