> CommandLineArgumentUsage class has a substring call but return value discarded:
> {code}
> if( input.get(0).length() > width ){
>                     String tooLong = input.remove(0);
>                     tooLong.substring(0, width-5);
>                     input.add("Command removed. Too long.");
>                 }
> {code}
> FindBugs also finds a static field should be final:
> {code}
> protected static List<String> instructions = new ArrayList<String>();
> {code}
