 According to Programming languages - C++
 Digit grouping is checked. That is, the positions of discarded
 separators is examined for consistency with
 use_facet<numpunct<charT> >(loc ).grouping()[[BR]]

 BUT what if there is no separators at all and grouping()
 is not empty? Well, we have no extraced separators, so we
 won`t check them for consistency. This will allow us to
 work with "C" locale from other locales.[[BR]]

 Moreover, looks like some implementations of STL use this approach.
