@end defun
@defun last* x &optional n
This function returns the last cons, or the @var{n}th-to-last cons,
of the list @var{x}. If @var{n} is omitted it defaults to 1.
The ``last cons'' means the first cons cell of the list whose
@code{cdr} is not another cons cell. (For normal lists, the
@code{cdr} of the last cons will be @code{nil}.) This function
returns @code{nil} if @var{x} is @code{nil} or shorter than
@var{n}. Note that the last @emph{element} of the list is
@code{(car (last @var{x}))}.
The Emacs function @code{last} does the same thing
except that it does not handle the optional argument @var{n}.
@end defun
@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.
