DEFUN / DEFMETHOD / DEFGENERIC lambda list indentation works currently like so: (defgeneric shared-initialize (instance slot-names &rest initargs &key &allow-other-keys)) whereas (defgeneric shared-initialize (instance slot-names &rest initargs &key &allow-other-keys)) would be preferred (aligning &KEY with INSTANCE, not SLOT-NAMES.)
