[RFC] moneypunct<wchar_t>: mbsrtowcs or just btowc?

Well, I'm also under this impression. The C standard mentions here
ISO 4217. Is this consistent with your reading?

> The fourth character (if present) is a space, right?

Well, the standard doesn't say this explicitly, talks about "character
used to separate the international currency symbol from the monetary
quantity". The glibc docs point out "(often a space)"

Now, this "often space" ;) is part of the currency symbol or not for
our purposes? Humm... Now that I think more about this, I'm sure that
another implementation thinks (at variance with current v3) that is 
*not* part of the currency symbol...

Paolo.
