variable substitution can't swap it back again. Fixed multiple recoding to include many TRULY-THE's in the expansion so that the resulting shift-and-add code would actually open coded. Added comprehensive handling of arithmetic and logical identities when an arg is -1, 0 or +1. Fixed the (- 0 x) ==> (%negate x) transform to be inhibited when the 0 is more contagious than X, or is -0.0.
