Description

@rodinalex

HypergeometricFunctions._₂F₁(0, 0, 1 / 2, 5 / 4) throws a domain error as "asin(x) is not defined for |x| > 1"
HypergeometricFunctions._₂F₁general(0, 0, 1 / 2, 5 / 4) works fine

    Generally when a or b is zero, the result should be 1.0. This is verified in weniger but not in general call. For example HypergeometricFunctions._₂F₁(0.5,0.0,1.5,1) returns NaN.
