Comment (by mstreng):

 While you're at it, could you change the wording in the first line of the
 documentation of has_cm for elliptic curves over the rationals to be less
 ambiguous?

 I've seen Complex Multiplication to mean over the base field and to mean
 over the algebraic closure, so "Returns True iff this elliptic curve has
 Complex Multiplication." is ambiguous. It could be "Returns True iff this
 elliptic curve has Complex Multiplication over the algebraic closure." or
 "Returns True iff this elliptic curve has a CM j-invariant." as in the
 number field case.
