Kludge up wrong-number-of-arguments error parsing for entities.

Before:

   (min)
   ;The procedure #[compiled-procedure 11 (min "arith" #x16) #x1b1a #x1c8ac2] has been called with 1 argument; it requires at least 2 arguments.

After:

   (min)
   ;The procedure #[arity-dispatched-procedure 11 min] has been called with 0 arguments; it requires at least 1 argument.

Screw cases be damned.
