Put the following in your .emacs file. It redefines the function
line-move to put the present line number in the status line. 
One limitation is the line number only gets modified when the
function next-line (or previous-line) is called. It does not
change for C-v or esc-v.




(defun set-line ()
  (interactive)
  (setq mode-line-process
        (format " %4d" (1+ (count-lines 1 (point))))))

;;; redefine new-line-move to include
;;; output of line number

(defun new-line-move ()
  (fset 'old-line-move
	    (symbol-function 'line-move))
  (fset 'line-move
	    (function
	     (lambda (arg)
	       (old-line-move arg)
           (set-line)))))

(new-line-move)
