Comment (by bruno):
I am sorry if I am becoming painful...
* I would allow more general integers in `generic_power_trunc` to allow
computations as follows:
{{{#!python
sage: R.<x> = PolynomialRing(ZZ, sparse=True)
sage: p = x^2^100 + 1
sage: p.power_trunc(100, 2^100+1)
100*x^1267650600228229401496703205376 + 1
}}}
* A curiosity question: Why did you write `generic_power_trunc` outside
from any class?
