 List notations for wider connectives; the Prop connectives have a fixed
 width so as to avoid iterated destruction (we go up to width 5 for /\, and
 width 4 for or). The bool connectives have arbitrary widths, but denote
 expressions that associate to the RIGHT. This is consistent with the right
 associativity of list expressions and thus more convenient in most proofs.  **)
