Changes (by AlexGhitza):

  * 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
              hyperelliptic curve is broken
  * milestone:  sage-3.4.1 => sage-3.3

Comment:

 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.
