Comment(by kcrisman):
This is not a problem about `latex()`.
{{{
sage: var('phi,y')
(phi, y)
sage: phi*y
phi*y
sage: latex(phi*y)
\phi y
}}}
It's a problem in `E.latex()`:
{{{
elif b[2]:
s += "+ %sy "%a[2]
}}}
Umm, yeah. Probably the intended use case is
{{{
sage: L.<z>=NumberField(x^2-x-1)
sage: b = z
sage: F = EllipticCurve([0,0,b,27*b-43,-80*b+128])
sage: latex(F)
y^2 + zy = x^3 + \left(27 z - 43\right)x + \left(-80 z + 128\right)
}}}
So do you think that a one-whitespace change would fix this? (Actually,
there are a few similar places.)
