REVISION SUMMARY
  We recently marked other legacy commands as only available to version 1
  of the wire protocols. We held off marking "between" because it is
  used as part of the SSH handshake.
  
  Since SSH servers assume they are version 1 by default and the
  "between" request that is issued as part of the version 2 handshake
  is swallowed and not operated on, everything should "just work" if
  "between" is not available to version 2.
