#4809 integrate(sqrt(x^2+x^3),x,-1,1) asks for the sign of x

[David Scherfgen]

I think integrate should never ask for the sign of the integration variable.

(%i1) integrate(sqrt(x^2+x^3),x,-1,1);
Is x positive or negative?

[Gunter Königsmann]

It definitely should know that in the current example its sign can be both.
