REVISION SUMMARY
  This is a followup to D7603 <https://phab.mercurial-scm.org/D7603> (49fa0b31ee1d <https://phab.mercurial-scm.org/rHG49fa0b31ee1d84c44eab951f36fb7386e3fced22>) which broke
  the tests for pure Python implementation. There are two
  divergences between pure and C implementations:
  
  - the pure implementation would accept only -1 as slice end, whereas C accepts both -1 and len(index)
  - in pure Python, `headrevs` is provided by revlog.py, not by the index.
