I didn't check my numbers.  If the current behavior is '%.6g','%.15g'
then we should stay with that as the default.

Hmm, on looking at the code, this might mean we need some configure
pushups to extract FLT_DIG and DBL_DIG and put those into the default
strings.  Do we support any platforms where these are not 6 & 15?
