[William Jon McCann <mccann src gnome org>]

commit 26d50b6e9fd4db7b47733a80a5ab6be2cb283571
Author: Ray Strode <rstrode redhat com>

    Add new gdm_user_is_logged_in method
    
    Before we were doing
    
    if (gdm_user_get_num_sessions > 0)
    
    all over the place.  This is slightly
    more clear.
