... for concreteness, this is what I actually tested. Seems safe to me,
being restricted to string / wstring (eg, no problem with basic_string
specializations), I can't see how the user could detect the
optimization. I'd like to apply the change in order to continue
experimenting with the nice idea...

Thanks,
Paolo.
