Granted, if there is a trailing space then you will not get the warning. Semantically though, neither do you have a
space separated format if you have a trailing space. Or it is a space separated format with a NULL last element. To my mind, whenever you have a something separated list, number of items plus number of separators is always odd. I'm not sure you could read too much into
narashima's formatting given that no code was shown or <code> tags used.
