	* Makefile.in (locallisppath): Make this default to
	${datadir}/emacs/site-lisp, instead of

	lock.
	(lisppath): Add ${externallispdir} to this.
	* INSTALL: Adjust installation directions.

	* Makefile.in (externallispdir): New variable, to say where to

	(COPYDIR, COPYDESTS): Copy the external lisp directory just like
	the others.
	* INSTALL: Describe external-lisp and the new externallispdir
	variable.
