New description:
Polynomials over the padics can be initialized from dictionaries.
{{{
sage: R.<t> = Qp(3)[]
sage: f = R.one()
sage: R(f.dict())
}}}
However, this fails for empty dictionaries:
{{{
sage: f = R.zero()
sage: R(f.dict())
ValueError: max() arg is an empty sequence
}}}
The attached patch fixes this.
