Currently we have
{{{
sage: Fx.<x> = GF(2)[]
sage: p = x + 1
sage: p.reverse(degree=5)
x^5 + x^4
}}}
However:
{{{
sage: Qx.<x> = QQ[]
sage: p = x + 2
sage: p.reverse(n=5)
2*x^4 + x^3
}}}
So not only is the name of the optional arguments different, it also has
subtly different semantics.
The optional argument should be the same, and `degree` makes most sense,
and the behaviour should be the same.
Overview of some other base rings:
* `ZZ` is like `GF(2)`
* `RR` takes NO keyword
* `CC` is like `GF(2)`
* `GF(p^m)` is like `GF(2)`
* generic base ring is like `GF(2)`
Are there other to check?
