    pager: fixing infinite looping error introduced in the previous commit.
    
    This workaround for WNCK pager layout limitations is getting ugly.
    We might be better off adding our own pager inheriting most of the 
functionality from WNCK.
    This might be needed in the future anyway as workspace ordering in the 
vertical WNCK pager is different from what we want and there is no easy 
workaround for this.
