options, and configuration keywords from the server documentation and
examples. ok jmc@

Use 2001:db8::/32, the official IPv6 subnet for
configuration examples.
This makes the IPv6 example consistent with IPv4, and removes a dubious
mention of a 6bone subnet.

since these pages now clearly tell folks to avoid v1,
normalise the docs from a v2 perspective (i.e. stop pointing out which bits
are v2 only);

Replace list of ciphers and MACs adjacent to -1/-2 flag

Add a similar warning to the Protocol option descriptions in ssh_config(5)

Provide a warning about chroot misuses (which sadly, seem
to have become quite popular because shiny). sshd cannot detect/manage/do
anything about these cases, best we can do is warn in the right spot in the

correct description of what will happen when a
AuthorizedKeysCommand is specified but AuthorizedKeysCommandUser is not (sshd
will refuse to start)

remember which public keys have been used for
authentication and refuse to accept previously-used keys.
This allows AuthenticationMethods=publickey,publickey to require
that users authenticate using two _different_ pubkeys.
