I did that. It turned out that the compiler num_get implementation
finishes like this:
if (__beg == __end)
__err |= ios_base::eofbit;
return __beg;
So, if there's nothing after the last character part of the number being
read, the eofbit is set, invalidating the read itself!
I don't know if this is a bug (it seems so to me), but anyway...
Note that it would suffice appending any character not being part of
the current numpunct facet, so the '\0' is pretty ok.
I'll add a comment to the code, in case someone wants to do a cleanup ;-)
