REVISION SUMMARY
  This make sure we have a properly created, fully functional repository early.
  This will be useful to simply the hardlink/copy phases of the local clone to
  make it share more of its logic with the similar "stream" cloning.
  
  This has a minor impact of the test and the resulting repository has is better initialized (eg: the `wcache` directory is pre-created.)

REPOSITORY
  rHG Mercurial

BRANCH
  default
