documentation bug, the documented example leads to: io.vertx.core.cli.MissingValueException: The option 'help' requires a value

when i use

addOption(new Option()
                    .setArgName("help")
                    .setShortName("h")
                    .setLongName("help"));

and type a command like

% shadowone -h

i get

i believe it should work as described here:
http://vertx.io/docs/vertx-shell/java/#_command_arguments

Start with the documented addOption example and the command arguments documentation linked in the issue. Trace the reported failure through DefaultParser.checkRequiredValues in the stack trace, then verify the behavior of -h; done means the documented example behaves as described without requiring an argument.
