#10152: bug in integral_points (for elliptic curves over Q)
-------------------------------+--------------------------------------------

Comment(by cremona):
More data points: with E=2082a1 and using the S_integral_points function,
with S=[2] or S=[3] the coefficient bound used is 11, while with S=[2,3]
it is 13 and the extra integral point is found! Clearly, a priori,
enlarging S should not ever reduce this bound, so something is wrong
there. This shows that both integral_points() and S_integral_points()
need fixing.
