drush ul does not work on subdirectory (d8)

If you use drush uli with Drupal 8 on a subdirectory drush uli generates
the following url:

    http://www:/user/reset/1/1378548300/PPxZXqpSCWbeDxAY6kiSpYwJvbnOrkRaMwJR4Xi6RZ4/login

The drushrc.php looks like the following: 

    <?php
    $options['l'] = 'http://www/d8';
    $options['url'] = 'http://www/d8';

This change currently changes the url to use:

    http://www/user/reset/1/1378548300/PPxZXqpSCWbeDxAY6kiSpYwJvbnOrkRaMwJR4Xi6RZ4/login

NOTE: This does not work yet.
