Patch to implement the 3rd option

The last option from my previous message seems, at least, unlikely to break
anything. Attached patch resolves this issue.

It also fixes a small unrelated bug that prevents the first byte prior to any
hex-escaped byte from being output, which was revealed by new self-test cases
that I have added.
