[Bug-gsl] bug: gsl_sf_bessel_zero_Jnu(double nu, unsigned int s)

[Michael Gilbert]

Hi,

If nu is negative, gsl_sf_bessel_zero_Jnu(nu, s) returns an error.  This 
is a  trivial because Jnu(-x, s) = Jnu(x, s), so to handle the issue i 
just do gsl_sf_bessel_zero_Jnu(fabs(x), s).  I think this would be an 
easy bug to fix.
