            Bug ID: 3378
           Summary: Make "Shared connectio to <host> closed."
message
                    silencable
           Product: Portable OpenSSH
           Version: 8.8p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: enhancement

Change "Shared connection ..closed" message from "always" to
VERBOSE

The message "Shared connectio to <host> closed." cannot be
silenced
without silencing ALL messages from ssh.

Please change it to be of LogLevel INFO, or VERBOSE, or add a config
option to silence it (e.g. MuxMessages default yes).

```
$ ssh -t daplane ls > /dev/null
Shared connection to 172.16.16.1 closed.
$
```

I understand that there are workarounds (e.g.,don't use -t, but
sometimes the remote tool needs a tty); however, one should be able to
silence the message (e.g., change LogLevel to ERROR) without silencing
ERROR and FATAL messages.

Attached is a simple patch that should suffice.

It is silenceable though. "ssh -q" or setting LogLevel=quiet stops it

@djm  Yes, -q or LogLevel=QUIET silences it, but that also silences
even FATAL and ERROR messages.  If it we set to an actual LogLevel,
then one could set LogLevel to ERROR and silence it while still
receiving ERROR and FATAL messages, should they occur.
