[feature suggestion] sshd should log the listening port number while logging errors/warnings

[Yuri]

I have sshd listening on several ports for various reasons.


sshd periodically logs errors like these:

 > Jun  4 22:52:52 xx sshd[30708]: error: 
Fssh_kex_exchange_identification: banner line contains invalid characters


This message would be a lot more helpful if it would contain the port 
number for this connection.

It would be easier to figure out where offending connections come from.


Thanks,

Yuri
