Of course, it's fairly simple to guess in this case which the two DSA keys
are - they're the matching pair for the properly-identified RSA keys. But
it's not ideal.
On further investigation, I'm not convinced that the DSA keys actually _have_
comments. Whether this is because the DSA keys _can't_ have comments, or whether
ssh-keygen -d just doesn't add them by default, I don't know.
You are correct. SSH protocol v.2 keys (RSA and DSA) do not have comments which
are sent over the wire like SSH v.1 keys.
Seems to be a feature.
