GNU Emacs 18.51.22 of Mon Sep 19 1988 on rjeinc (usg-unix-v)

There's a bug in lpr.el which makes lpr-buffer inoperative on this SysV.

The code for lpr.el correctly accounts for UnixV versus BSD by the code
segment:

     (apply 'call-process-region
	    (nconc (list start end (if (eq system-type 'usg-unix-v)
				       "lp" "lpr")
			 nil nil nil
			 "-J" name "-T" name)
		   switches))

which tells emacs to expect to run the "lp" program rather than "lpr",
but the switches that are passed to lp (-J and -T) are unknown to lp.
The lp program responds by: '/usr/bin/lp: unknown keyletter "-j"'
(a message which we actually don't see since the BUFFER arg to
call-process-region is nil).

Result: call-process-region returns, no output on printer.
This can be fixed by replacing the above with:

     (apply 'call-process-region
	    (nconc (if (eq system-type 'usg-unix-v)
		       (list start end "lp" nil nil nil
			     (concat "-t" "\"" name "\""))
		     (list start end "lpr" nil nil nil "-J" name "-T" name))
		   switches))
