I get a test failure when I run the test suite with unittest.patch:

test_Exit (unittest.test.test_program.Test_TestProgram) ... test test_unittest crashed -- Traceback (most recent call last):

AssertionError

The new patch (see issue18381.diff) fixes that failure. Other changes:

* Added documentation
* Added a test case for addWarning and TestResult.warnings
* Added "print warning" feature
