Long command line arguments do not work properly #71

Long command line arguments is chosen even though its full name hasn't been provided. Given command line argument: erd --ed Should output: unrecognized option "--ed" But instead it outputs: option "--ed" requires argument EDGE It seems that if just part of the name of the argument matches, it matches the option with the corresponding full name. ( i.e --ed matches to --edge ) I don't know whether this is intentional but I'm guessing that it isn't.

I have checked the original GNU getopts ( haskell getOpts is just a port of it) and it is intended behaviour. Im closing this then
