If you havd a sshd that is compromised in the same way as one was on one of my

I don't know what relevance this has to a discussion of OpenSSH logging
I'd like to have OpenSSH log the email address field from a key that was used
for login so I could see something like "ssh key firstname.lastname@example.org was used
to login to account rjc" in my logs.
