[issue11218] pattern=None when following documentation for load_tests and unittest.main()

[Michael Foord]

Michael Foord <michael at voidspace.org.uk> added the comment:

So the logic of the "pattern" argument to "load_tests" is that it should not be None when test discovery is loading the __init__.py module of a test package. However, because most patterns will actually *prevent* __init__.py from being loaded by test discovery - this turns out to not be very useful and in all practical cases this argument will be None.

I don't think there are any backward compatibility issues with the real pattern being passed in.
