Tom, did you implement this functionality in *printf?
The size may be given as zero to find out how many characters are
needed; in this case, the str argument is ignored. Sprintf() and
vsprintf() effectively assume an infinite size.
Looking at the code it doesn't seem supported. Should it be added to
the limitations comment section?
