Well, A) I've probably only written 20 lines of LISP in my life and
B) Entirely disabling bracketed paste mode and this are a bit orthogonal...
there's a case for both to be sure, given bracketed paste mode is
arguably the wrong side on which (and method with which) to fix the
paste-hijacking security issue and you may want paren-finding and other
things turned on during a paste for some reason.  Also C) I think it's a design
issue that maybe deserves some discussion rather than arbitrarily adding
more spaghetti variables/directives.
