     [channels.c]
     When we added support for specified bind addresses for port forwards, we
     added a quirk SSH_OLD_FORWARD_ADDR. There is a bug in our handling of
     this for -L port forwards that causes the client to listen on both v4
     and v6 addresses when connected to a server with this quirk, despite
     having set 0.0.0.0 as a bind_address.
     report and patch from Jan.Pechanec AT Sun.COM; ok dtucker@
