/* Compare an input string filtered through the QP encoder to the expected output.
We iterate over all possible split points, testing interruption of the write
between all input characters, with zero-to-three one-character runs at the split,
so we should single-step through all states.
We then feed it back through the decoder to make sure it survives a round-trip.
