Toned down note in docs (at Raymond's request) in r65366.
While I'd really like to see an lsum-based version go in instead, I
think it's too close to the release to make this change right now.
There was also originally some talk of a complex math version. What do
people think about this? Personally, I suspect that the use cases would
be few and far between, and anyone who *really* needs a complex high-
precision sum can just apply math.fsum to real and imaginary parts.
(This is easier now that x.imag and x.real make sense for integers as
well as floats.)
