New issue 3626 by skirpic...@gmail.com: Wrong order and series coefficients
for expint()
http://code.google.com/p/sympy/issues/detail?id=3626
In [36]: expint(S(3)/2,-x).series(x,0,5)
Out[36]: 2 - 2*sqrt(pi)*sqrt(-x) - 2*x - x**2/3 - x**3/15 + x**4/12 +
O(x**5)
^^^^^^^
vs
In [37]: expint(S(3)/2,-x).series(x,0,7)
Out[37]: 2 - 2*sqrt(pi)*sqrt(-x) - 2*x - x**2/3 - x**3/15 - x**4/84 +
x**5/60 + x**6/360 + O(x**7)
