Update to 2.6.2:

2.6.2
-----------

- Added function pytest.freeze_includes(), which makes it easy to embed
  pytest into executables using tools like cx_freeze.
  See docs for examples and rationale. Thanks Bruno Oliveira.

- Improve assertion rewriting cache invalidation precision.

- fixed issue561: adapt autouse fixture example for python3.

- fixed issue453: assertion rewriting issue with __repr__ containing
  "\n{", "\n}" and "\n~".

- fix issue560: correctly display code if an "else:" or \ 
"finally:" is
  followed by statements on the same line.

- Fix example in monkeypatch documentation, thanks t-8ch.

- fix issue572: correct tmpdir doc example for python3.

- Do not mark as universal wheel because Python 2.6 is different from
  other builds due to the extra argparse dependency.  Fixes issue566.
  Thanks sontek.
