Fixed the C-- lexer to comply with the standard on hex escape sequences.
The C-- standard [1] says in Section 3.3.5 "Character literals" that:
 - the hex escape sequence "must contain at least one and
   at most two hexdigits."
 - the octal escape sequence "must contain at least one and
   at most three octdigits."
