+*nix systems use \n line endings, while Windows systems use \r\n. Python
+handles this using universal newline mode for reading files. Let's make
+sure doctest does so (issue 8473) by creating temporary test files using each
+of the two line disciplines. One of the two will be the "wrong" one for the
+platform the test is run on.

+Windows line endings first:
+
+ >>> import tempfile, os
+ >>> fn = tempfile.mktemp()
+ >>> with open(fn, 'w') as f:
+ ... f.write('Test:\r\n\r\n >>> x = 1 + 1\r\n\r\nDone.\r\n')
+ 35
+ >>> doctest.testfile(fn, False)
+ TestResults(failed=0, attempted=1)
+ >>> os.remove(fn)
+
+And now *nix line endings:
+
+ >>> fn = tempfile.mktemp()
+ >>> with open(fn, 'w') as f:
+ ... f.write('Test:\n\n >>> x = 1 + 1\n\nDone.\n')
+ 30
+ >>> doctest.testfile(fn, False)
+ TestResults(failed=0, attempted=1)
