The block of code that canonicallizes the hostname supplied on
the command line added by patch-ssh.c misapplies to 7.7p1 and
moves from main() to to ssh_session2(). This breaks ssh SSHFP
support for non-canonical hostnames. For example, "ssh zinc"
correctly discovers the FQDN (zinc.ee.lbl.gov) and uses it to
look up A and AAAA records but the non-canonical version (zinc)
is used in the SSHFP record lookup which or course fails.

Regenerate the patch.
