OK, but that's not exactly what I asked.  The question is, is one of those
public keys (/home/cevans/.ssh/id_rsa.pub, /home/cevans/.ssh/id_dsa.pub, or
/home/cevans/.ssh/id_ecdsa.pub from the client) in ~/.ssh/authorized_keys
on the server?

Correct, see AUTHORIZED_KEYS FILE FORMAT in sshd(8).

> The lines in the authorized_keys file begin with ssh-rsa ..., ssh-dss ..., 
> ecdsa-sha2-nistp256 ....  The lines all end with a white space and

OK, so the answer to that is no.
