Wrong detecting overlaps for contiguous Intervals

[ssic7i]

.overlaps working wrong when intervals are contiguous
examples:

I.closed(1, 2).overlaps(I.closed(2, 3))
True
I.closed(1, 2).overlaps(I.closedopen(2, 3))
False (should be True)
I.closed(1, 2).overlaps(I.closed(2, I.inf))
False (should be True)

---

I.closed(2, I.inf).overlaps(I.closed(1,2))
False (should be True)
I.closed(2, 3).overlaps(I.closed(1,2))
True
I.closedopen(2, 3).overlaps(I.closed(1,2))
False (should be True)

I'm back from holidays. I'll have a look asap. This bug wasn't catch by the test suite because of the permissive flag. Sorry for that.

Bug is fixed in 1.5.4, available in a few minutes on PyPI.
