0.8.14.16: Zipper Up
            * Fix deftype lambda-list parsing to bind unsupplied
               keyword parameters to * instead of NIL if no initform
               was supplied -- only one of the four cases used to be
               handled correctly. Reported by Johan Bockgård on #lisp
            * Fix #347: define-compiler-macro lambda-list parsing
               binds correctly when FUNCALL appears as the car of the
               form (port of Raymond Toy's fix for the same from
               CMUCL). Also reported by Johan Bockgård.
            * In course of fixing the latter, make simple but
               philosophically profound change to parse-defmacro: what
               was error-kind is now thought of as a context marker.
            * Tests, tests, tests
