---------------------------------
Is a patch for 2.0 still needed?
> [cli] Unknown options are ignored instead of throwing
> UnrecognizedOptionException
> ---------------------------------------------------------------------------------

> CLI does not handle unknown options, i.e. throw an
> 'UnrecognizedOptionException'.
> The reason is that the logic of PosixParser.processOptionToken() is
> incomplete:
> if (this.options.hasOption(token))
> {
> currentOption = this.options.getOption(token);
> tokens.add(token);
> }
> else if (stopAtNonOption)
> {
> eatTheRest = true;
> }
> ie. if the stopAtNonOption is not set and the token is unknown, it
> will be ignored. there has to be a default case added:
> else {
> tokens.add(token);
> }
> in which case the caller will throw the proper exception, because
> in Parse there is another check whether the option exists.
> i would've submitted a patch but did not find where to, sorry.
