New issue 4060 by [email protected]: Wrong result for integrate(1/(x - y), (x, y - 1, y + 1))
http://code.google.com/p/sympy/issues/detail?id=4060

x, y = symbols('x y')
integrate(1/(x - y), (x, y - 1, y + 1))
-I*pi

The function has a pole at a. The integral has a Cauchy principal value of zero. Returned value should be 0.
