Comment (by vbraun):
It would be less confusing if we also wrap GiNaC unit and primpart and
copy in some of the documentation
{{{
The methods
ex ex::unit(const ex & x);
ex ex::content(const ex & x);
ex ex::primpart(const ex & x);
ex ex::primpart(const ex & x, const ex & c);
return the unit part, content part, and primitive polynomial of a
multivariate polynomial with respect to the variable ‘x’ (the
unit part being the sign of the leading coefficient, the content
part being the GCD of the coefficients, and the primitive
polynomial being the input polynomial divided by the unit and
content parts). The second variant of primpart() expects the
previously calculated content part of the polynomial in c, which
enables it to work faster in the case where the content part has
already been computed. The product of unit, content, and
primitive part is the original polynomial.
}}}
This is `FactorTermsList[poly, x]` in Mathematica, so perhaps we can have
a non-underscore method that returns all three?
