the count method returns the wrong value

Created by: tflori

The count method should return the count of options given in the command line. But it actually gives the count of options with short and long name. This differs also from the count of the ArrayIterator.

To reproduce:

$getopt = new Getopt([
  new Option('a', 'alpha'),
  new Option('b', 'beta'),
]);

$getopt->parse('-ab');

$count = $getopt->count(); // this should be 2 but it is 4
$iterator = $getopt->getIterator();

var_dump($count === $iterator->count());
