Thanks Benjamin for your feedback.
I completely agree with you. In the next couple of days I will work on 
_M_widen_int (and the corresponding projected output) to enable grouping 
for hexs and octs. The only tricky point is that we cannot simply change 
the condition if (__grouping.size() && __dec) to (__grouping.size())) 
since, as is, __add_grouping is not able to deal correctly with numbers 
beginning with 0x or 0X or 0 (when showbase is true, I mean). But I can 
work out this.
As regards the impact on other testsuite files, I will see what breaks 
and in case I'm not able to sort out the problem I will ask for your help.

Ciao, Paolo.
