// Instead of splitting URLs and extract path components, we can implement
// CanonicalURLStringCompare() using string operations only. The key idea is,
// treating '/' to be less than any valid path characters would make it behave
// as a separator, so e.g., "test" < "test-case" would be enforced by
// "test/..." < "test-case/...". We also force "?" < "/", so "test?query" <
// "test/stuff". Since the routine is merely lexicographical string comparison
// with remapping of character ordering, so it is a valid strict-weak ordering.
