 Byte literals are defined with single quotes.
 The following additional escape sequences are allowed in byte literals:
 
-    \xnn    // arbitrary byte value defined as a 2-digit hexadecimal number
+    \xnn   // arbitrary byte value defined as a 2-digit hexadecimal number
     \nnn   // arbitrary byte value defined as a 3-digit octal number
 <!-- jba: this contradicts the spec, which has \nnn (no leading zero) -->
