    Look for FamilyLocal if inet or inet6 address is loopback
    
    libxcb uses FamilyLocal authorization if the host name or IP in the
    display string is from the loopback device. This patch adds the same
    behavior to xauth.
    This fixes a long standing problem that for ssh tunneled connections
    a display variable of the form: localhost:<N>.<M> leads to correct
    authorization when an X client is started but "xauth list $DISPLAY"
    returns nothing.
