Patch for copyright.el to allow multi-line copyrights

[Lars Magne Ingebrigtsen]

When updating lines as the following, copyright.el will add
"2002" to the end of the first line.  The patch below fixes this. 

;; Copyright (C) 1987, 1988, 1989, 1990, 1993, 1994, 1995, 1996 
;;        1997, 1998, 2000, 2001, 2002 Free Software Foundation, Inc.
