Formatting a large number with a locale

[Cory Nelson]

I have some very large numbers that don't fit in any of the standard
(or non-standard) builtins. I can make these base-10 ascii easily,
but I would like to use a locale for nice l10n support. Is there any
solution to this? I see the std::num_put facet but it only takes
builtins.

There's also a num_punct facet which num_put uses. You can use
it.
