It is not antisymmetric.

	prefixcmp("foo", "foobar") < 0
	prefixcmp("foobar", "foo") == 0

I can see how it's possible to care about the sign of the return
value, but it's equally possible to care about the sign from
suffixcmp.  Neither is suitable as a function for passing to qsort.

Hoping that clarifies,
Jonathan
