// We test the following cases:
// - no match in string. Do we miss the end condition? Will crash if we read
// past the string.
// - no match in string, but after the string there is a match.
// Do we incorrectly report this match? We had a case where we stepped
// a few chars past the string, this test would report that error. The
// one above would not.
// - The needle is exactly at the end of the string.
// - The needle spans the end of the string
//
// A special case are needles of length 1. For these we test:
// - needle is first char
// - needle is last char
// - no match
// - match behind string.
//
// We test all these for an unknown needle, and needles known to the compiler
// of lengths 5, 2 and 1.
