Comment(by malb):
Patch looks good (small issue see below), applies cleanly, doctests pass.
So, this stuff now works, very cool:
{{{
#!python
sage: P = PolynomialRing(GF(127),2,'x',order=Matrix([1,2,0,3]))
sage: P.term_order()
Matrix term order with matrix
[1 2]
[0 3]
sage: magma(P)
Polynomial ring of rank 2 over GF(127)
Order: Weight [full]
Variables: x0, x1
sage: singular(P)
// characteristic : 127
// number of vars : 2
// block 1 : ordering M
// : names x0 x1
// : weights 1 2
// : weights 0 3
// block 2 : ordering C
}}}
I've attached a small referee patch which Kwankyu or someone else has to
sign of. Kwankyu's patch gets a positive review modulo the issue in the
referee patch.
