Use "inc" instead of "func" in the snipped on README

"inc" reads better, also fixed the line separators so
they have the same size

 Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used. See `getting-started <http://docs.pytest.org/en/latest/getting-started.html#our-first-test-run>`_ for more examples.
