Comment:
Rebased on 6.2.beta8. I changed the implementation of
`LaurentPolynomial.is_monomial` because it gave the wrong (in the sense of
#11747) result. It would also have marked zero as a monomial which would
be wrong IMHO, and not according to `Polynomial.is_monomial`. I also
changed the documentation to fit #11747. I removed the words `non-
negative` from the doc of the `laurent_polynomial.pyx` implementation. I
finally fixed appearances of "Returns".
