REVISION SUMMARY
  For backwards compatibility reasons. We want extension provided
  commands to opt in to version 2 rather than get inherited
  automatically. This will facilitate a clean break between the
  protocols.
  
  As part of this, we duplicate some commands used in tests so
  there are different command handlers per transport.

REPOSITORY
  rHG Mercurial
