What's the 0 for? 0alloc'd?

You are also allowed to realloc() a null pointer, or a pointer returned
by a previous successful call to realloc() that has not yet been free()d
or successfully realloc()d again. As far as I can see, those are the
only two things this code ever realloc()s. Have I missed something?
