[PATCH] remove hardcoded selection for HEX ESCAPES(???)

[Robert P. J. Day]

  (if this patch is appropriate, feel free to apply it.  it removes
the hardcoded setting of the macro WANT_HEX_ESCAPES plus the
subsequent conditionals based on it.  it's not clear whether it makes
much sense to have that kind of conditional proprocessing if it's
not a menu configuration selection.  it's also not clear why you
*wouldn't* want hex escapes but if there's a good reason to keep
supporting that, then feel free to toss this patch.)
