dc01a8edd4 Don't display the MOTD when an explicit command is run. 
(possibly via authorized_keys(5) restrictions), even when a
pseudo-terminal has been allocated for the session.  In other words,
only display the MOTD when the server starts the user's default shell.

da57dd13c5 Set tcp priority as follows: 
if (connecting || ptys || x11) tos = LOWDELAY;
else if (tcp_forwards) tos = 0;
else tos = BULK;

TCP forwards could be either lowdelay or bulk, hence the default priority.
