Message-ID: <1372338690045-290340.post@n5.nabble.com> (raw)

(defun copy-region-as-kill (beg end)
  "Save the region as if killed, but don't kill it.
     In Transient Mark mode, deactivate the mark.
     If `interprogram-cut-function' is non-nil, also save the text for a
window
     system cut and paste."
  (interactive "r")
  (if (eq last-command 'kill-region)
      (kill-append (filter-buffer-substring beg end) (< end beg))
    (kill-new (filter-buffer-substring beg end)))
  (if transient-mark-mode
      (setq deactivate-mark t))
  nil)

What is the "nil" doing at the end here? The syntax seems to be:

(defun copy-region-as-kill (beg end) [...] nil)
