New submission from Chris Jerdonek:
When newlines are present, the error message displayed by unittest's
self.assertEqual() to show where strings differ can be nonsensical. For
example, the caret symbol can show up in a strange location.
The first example below shows a case where things work correctly. The second
shows a newline case with the confusing display.
