--- Comment #6 from Albert Chan <albertmcchan at yahoo dot com> --- if gcc hex escape AND octal is right, does it contradict comment #1 ? "octal or hexadecimal ... longest sequence that constitute escape sequence" I noticed OLD python (2.0) also use the C rule regarding hex escapes, but later switch to a more sensible 2 hex = 1 byte rule (\xX or \xXX)
