Add kludge to work around `cl-defmethod' bug

`cl-defmethod' does not properly treat an argument that is named
`_', which causes `describe-function' to malfunction when trying
to describe a generic function that has a method that was defined
that way.  Rename the argument to `_rest' to work around this.
