I obviously overlooked the collision between \u - username and \uHHHH -
unicode. It could be dealt with by interpreting the escape as username if
the following character is non-hex, but that would stand a good chance of
breaking existing prompts. Since \U functionally is a complete superset of
\u - unicode, perhaps the latter wouldn't need to be duplicated for
prompting.
