Prior to this patch prefix_tree asserts.

This is because as it adds the 255th element at a node it attempts to calculate
the count member var which is an unsigned char via count = (255 -0) + 1; and
pass the result to realloc. Unfortunately the result is zero and realloc returns
null; the prefix_tree asserts. I have fixed it by making the count an unsigned
short.
