Inconsistency in skipif example

[zenhack]

The first two examples in this section of the documentation:

http://pytest.org/latest/skipping.html#skip-all-test-functions-of-a-class-or-module

Are internally inconsistent. The docstring for test_function says "will not be setup or run under 'win32' platform" (and the class name TestPosixCalls is suggestive of this), but the actual condition passed to skipif (as well as reason) is the opposite: the tests will only be run on windows

Good catch, thanks!
