Fix snprintfW Return Value

[Rob Shearman]

Hi,

At present, if the size of the buffer passed to snprintfW is too small
then the function returns -1, as opposed to the required size of the
buffer (as per C snprintf). This greatly limits its usefulness and can
give incorrect results for those using the function that don't
explicitly check for -1 being returned. A grep of the source tree shows
that nothing depends on this behaviour.
