Yes, sorry; I was thinking both were already closer to 2G and was
using an old idea (closer to 6G) for world population. So some more
work would be needed to get a good estimate.

Agreed. BTW if you support arbitrary radix characters, you should not
restrict it to ASCII; this then means the length in bytes of floating
point fields varies by locale (currently the only printf specifier
where either the contents OR length vary by locale is the nonstandard
one, %m) which affects asprintf (right now it's "broken" if it races
with setlocale and the format includes %m; I don't know if we care)
and the implementation of a lot of other stuff (like wprintf).
