-@defun butlast x &optional n
-This function returns the list @var{x} with the last element,
-or the last @var{n} elements, removed.  If @var{n} is greater
-than zero it makes a copy of the list so as not to damage the
-original list.  In general, @code{(append (butlast @var{x} @var{n})

-@defun nbutlast x &optional n
-This is a version of @code{butlast} that works by destructively

 @defun list* arg &rest others
 This function constructs a list of its arguments.  The final
 argument becomes the @code{cdr} of the last cell constructed.
