#7695: naming of the variable in subfields of cyclotomic fields
-----------------------------+----------------------------------------------

{{{
sage: F = CyclotomicField(7)
sage: K = F.subfields(3)[0][0]
sage: K
Number Field in zeta70 with defining polynomial x^3 + x^2 - 2*x - 1
}}}
I think this convention of adding a 0 to the variable name, as nice and
practicle as it is in general, is not good in this case. The resulting
algebraic element is not a 70th root of unity as the name would suggest.
