I just used '\x' in both 1.8 and 1.9. In 1.8, this is just a string
of two characters. In 1.9, I also expected this, but I got
"invalid hex escape". I'd very much expect this for "\x", but
I didn't expect hex escapes to suddenly work in single-quoted strings.

Was this discussed, or is this just an (unintended) artefact of
some other changes?

Regards,    Martin.
