Successful partial string comparison in Python doctests. Enable the use of ellipsis in string output checked by a doctest.

	# When comparing inexact strings in Python doctests, and using ellipsis,
	# be sure to follow the output generating statement with a comment:
	# "# doctest: +ELLIPSIS"

	# Reference: https://web.archive.org/web/20190806202840/https://pymotw.com/2/doctest/#handling-unpredictable-output

	# This tripped me up when first starting out with doctests. I would
	# output a string in which the end or middle was unimportant. I needed
	# to ensure only certain parts. The tests would always fail. This
	# turns on ellipsis processing when dealing with strings.
