I agree with that ... but why is it failing?  If the only reason it's
failing is because the buffer isn't big enough, that is wrong; it's
supposed to return the number of bytes it wanted to write.  My reading
of the code we have now is that it's correctly rejecting the case where
snprintf() returns -1.
