Done.  The API now looks like this:

  s = ustring::compose("%1 is lower than %2.",
                       12, ustring::format(std::hex, 16));

I opted to keep the method names compose() and format() rather than
switching to the boost names format() and group().  Since format() can
be used without compose() it would be strange to call it group():

  s = ustring::format(12.3);

Is that OK with you all?
