* summary: coordinate ring of an affine patch on a hyperelliptic curve
is broken => [with patch, needs review]
coordinate ring of an affine patch on a

The attached patch fixes the issue by making sure that the defining
polynomials for a subscheme are elements of the coordinate ring of the
ambient space.
