upstream commit
Drop compatibility hacks for some ancient SSH implementations, including ssh.com <=2.* and OpenSSH <= 3.*. These versions were all released in or before 2001 and predate the final SSH RFCs. The hacks in question aren't necessary for RFC- compliant SSH implementations. ok markus@ OpenBSD-Commit-ID: 4be81c67db57647f907f4e881fb9341448606138
