DEFGENERIC

[Dick Gabriel <RPG@SAIL.Stanford.EDU>]

The material for the behavior Moon specified does not look too bad
when presented this way: defgeneric does an ensure-generic-function,
it removes all methods defined by any previous defgeneric, and then
it adds the methods specified by the :methods. The DEFCLASS description
is similar.  The presentation is clear and more concise than the
desciption of the previous behavior. 

Anything more to change?
