     [auth2.c sshd_config.5 servconf.c]
     Remove ChallengeResponseAuthentication support inside a Match
     block as its interaction with KbdInteractive makes it difficult to
     support.  Also, relocate the CR/kbdint option special-case code into
     servconf.  "please commit" djm@, ok markus@ for the relocation.
