Yes. lexical_cast works, and obviously .c_str()/.length() could be used
but instead of a 50-odd line patch to boost.format that's a whole load
more changes to a lot of client code... plus whilst I don't care about
format performance, I'm not sure I don't care about it enough to not
care about additional string construction :)

Well I've attached my hack. I'm sure it's wrong in lots of ways but
kinda does the trick, for some definition of kinda.
