Agreed. That might be the strategy for 2.7.

But it depends on how much of the other float and int formatting code I
can re-use from 3.1. If I can hide the 2.7/3.1 differences in
PyOS_double_to_string, then the 2.7 and 3.1 code should be identical,
and the fix will be different in the 3.1 code base.

I'll decide in the next few weeks.
