--- Comment #1 from Damien Miller <djm at mindrot.org> ---
Yeah, the encoding is redundant - having the public key appended to the
private. I updated the PROTOCOL.agent file that is our best reference
for how private keys are serialised to mention this, but I don't think
we can trivially change it without breaking older OpenSSH clients,
since they check the length is what they expect.
