One way to work around https://github.com/googlei18n/cu2qu/issues/51
when using the ufoLib's ReverseConturPointPen via the converter pens
would be to pass the outputImpliedClosingLine=True argument
(False by default) to the PointToSegmentPen.
This way, all the final lineTos are explicitly outputted, even when
they are redundant and could be implied (i.e. when they are not
duplicate points).
Note that this test is skipped by the CI, because ufoLib is not a
dependency of fonttools; you can run locally if you wish.
