isfundamental() suggestion 

Hi,

(12:44:26) gp> N=-3^2000-2;
(12:44:28) gp> isfundamental(N)
  *** isfundamental: user interrupt after 4,610 ms.
(12:44:39) gp> nfdisc(quadpoly(N),1)==N
%141 = 1

For consistency, I think it makes sense to add flag=1 option to
isfundamental(). 

BTW, are there any known cases where nfdisc(pol,1)!=nfdisc(pol) ?

Thanks

Igor
