Description

Plotting 

E2 = EllipticCurve([0,0,0,-7,0])
plot(E2)

shows the entire EC, but 

E = EllipticCurve([-6,6])
plot(E)

does not, although there are points with positive x: 

E = EllipticCurve([-6,6])
print '\n'.join([ '%s'%E.lift_x(xp)for xp in srange(-2,5,0.5)])

This is possibly related to ​#5124 because e.g. plot(E, (-3,3)) is ignored and hence impossible to plot the entire picture of E.
