Re: Proposed elldata database at the PARI workshop 

Bug: when using a changed curve equation, ellgens() doens't transform
the generators:

gp> E=ellinit([0,50,0,609,0]);
gp> ellidentify(E)
%16 = [["9744C2", [0, -1, 0, -224, -816], [[-11, 14], [-10, 18]]], [1,
-17, 0, 0]]      /* <--- Note the coordinate change */
gp> ellgens(E)
%17 = [[-11, 14], [-10, 18]]

But this should be [[-28, 14], [-27, 18]].
