The delete-method function deletes a method from a specified action.
delete-method &key action title method error-p
The action argument is the action from which the method is to be deleted.
The title argument is a string which titles the method.
The method argument is a method.
If the error-p argument is t, an error is generated if the specified method cannot be found.
The delete-method function returns the deleted method, or nil if the method cannot be found and error-p is not set.
Calls to delete-method must supply either (1) action and title arguments, or (2) a method argument.
(delete-method :method (first (list-methods (fb move)))) ==>
