[sage-devel] Sign issue in special values of Legendre Polynomials

Hi, It seems the special values of the Legendre Polynomials evaluated at zero are hard coded to be positive, but the sign should alternate. So, while legendre_P(0,0) correctly gives 1 and legendre_P(4,0) correctly gives 3/8, legendre_P(2,0) gives +1/2 instead of -1/2. Evaluating legendre_P(2,x
