 Not so fast! :)

 I think we need an else condition, because `wp_parse_id_list( array() )`
 does return an empty array. But maybe the else condition should be
 explicitly not made to work, like `group_id = 0` or something. I was just
 wondering, could there be a passed arg that would be useful? I can't think
 of one.

 Thanks again for this good idea!
