Title: Replace & in source with &amp; in output

Sorry I missed this. To really preserve the original code and avoid needing to manually escape anything, we also need to replace `&` with `&` so that things like `©` are preserved in output.

Avoid accidental HTML entitites by escaping `&` in input with `&` so
that the code output can really be treated as raw code.
