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);

Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
better performance than plain DH and DSA at the same equivalent symmetric
key length, as well as much shorter keys.
Only the mandatory sections of RFC5656 are implemented, specifically the
three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
ECDSA. Point compression (optional in RFC5656 is NOT implemented).
Certificate host and user keys using the new ECDSA key types are supported.
Note that this code has not been tested for interoperability and may be
subject to change.

convert to new .Dd format;
(We will need to teach mdoc2man.awk to understand this too.)
[readconf.c readconf.h ssh-keysign.8 ssh-keysign.c]
we cannot use HostbasedAuthentication for enabling ssh-keysign(8),
because HostbasedAuthentication might be enabled based on the
target host and ssh-keysign(8) does not know the remote hostname
and not trust ssh(1) about the hostname, so we add a new option
EnableSSHKeysign; ok djm@, report from zierke@informatik.uni-hamburg.de
[ssh-keysign.8 ssh-keysign.c ssh.c ssh_config]
re-enable ssh-keysign's sbit, but make ssh-keysign read
/etc/ssh/ssh_config and exit if HostbasedAuthentication is disabled
globally. based on discussions with deraadt, itojun and sommerfeld;

add /usr/libexec/ssh-keysign: a setuid helper program for hostbased
authentication in protocol v2 (needs to access the hostkeys).
Note: Makefile.in untested. Will test after merge is finished.
