REVISION SUMMARY
  Hooks and extensions can rely on PYTHONPATH value. Yet the pyoxidized binary
  ignore the variable. So we manually reinstall the behavior to fix various tests
  and restore the expected behavior.
  
  This positively affects:
  
  - test-extension.t
  - test-hook.t

REPOSITORY
  rHG Mercurial

BRANCH
  stable
