[Q] Exiting on help message.

[jmervine]

I was able to get around this by copying the default HelpPrinter and adding an exit to the end, seems clunky though.

    cli.HelpPrinter = func (templ string, data interface{}) {
        w := tabwriter.NewWriter(os.Stdout, 0, 8, 1, '\t', 0)
        t := template.Must(template.New("help").Parse(templ))
        err := t.Execute(w, data)
        if err != nil {
            panic(err)
        }
        w.Flush()
        os.Exit(0)
    }
