util: fix another cunescape() regression
Fix a regression caused by 4034a06d ("util: rework word parsing and c unescaping code") which broke octal escape sequences. The reason for this breakage is that cunescape_one() expects 4 characters in an octal encoding, which is a stray left-over from the old code which operated on different variables to make the length check. While at it, add a test case to prevent the same thing from happening again.
