     [sshd.c]
     When in inetd mode, have sshd generate a Protocol 1 ephemeral server
     key only for connections where the client chooses Protocol 1 as opposed
     to when it's enabled in the server's config.  Speeds up Protocol 2
     connections to inetd-mode servers that also allow Protocol 1.  bz #440,
     based on a patch from bruno at wolff.to, ok markus@
