It should return a non-NULL (char array of length 1 with a zero in it)
and length == 0.

Obviously this will recurse forever if you don't read the separator
characters between the calls. Is this a problem though? It seems
important to me that you need to do this as otherwise you don't know
what exactly the separator char was.
