REVISION SUMMARY
  We just marked the changegroupsubset command as only available to
  version 1 of the wire transports. There is a capability of the same
  name of the command that indicates if the command is supported.
  
  This commit teaches the capabilities code to conditionally emit that
  capability depending on whether the command is available for the
  current transport.
  
  Most test output is reordering of capabilities. But the limited tests
  for version 2 of the SSH protocol do show the capability disappearing.
