[boost] basic_format operator= exception safety

I can't really understand the invariants of the basic_format class but I
suspect that its copy assignment operator has exceptions safety issue. In
case that the operator= is exception safe then it only provides the basic
guarantee and I wondered if it's was intentional?
Anyway, AFAIKT this function can easily provide the strong guarantee using
the usual swap idiom without any drawback.

Thanks,
Rani
