	(setq auto-mode-alist (append '(
				       ("\\.1$" . nroff-mode)
				       ("\\.2$" . nroff-mode)
				       ("\\.3$" . nroff-mode)
				       ("\\.4$" . nroff-mode)
				       ("\\.5$" . nroff-mode)
				       ("\\.6$" . nroff-mode)
				       ("\\.7$" . nroff-mode)
				       ("\\.8$" . nroff-mode)
				       ("\\.man$" . nroff-mode)
				       ("\\.me$" . nroff-mode)
				       ("\\.mm$" . nroff-mode)
				       ("\\.mr$" . nroff-mode)
				       ("\\.ms$" . nroff-mode)
				       ("\\.Z$" . z-mode)
				       ) auto-mode-alist))

The thing that caught me is that you must load the file containing the mode
definition or put it on your autoload list thus
   (autoload 'z-mode "z-mode" "Uncompress file" t)
otherwise you get a strange complaint about file syntax.
