Comment (by jpflori):
Further rants: in fact in (quadratic) number fields at least we always
have whatever > whatever else true and whatever < whatever else false.
Indeed, the _cmp_ functions test for equality, that is completely
understandable because there's no reason to decide that a root of a
polynomial is "positive" or "negative" without chosing an embedding
somewhere...
But I is defined with embedding=CC.gen(), i.e. the usual definition, and
so we have CC(I) considered as "positive" (no surprise here...).
