(lpr-headers-switches): Treat hpux like usg-unix-v.

(print-region-1): Adjust start, end after running pr.

(lpr-command): Use dgux, not dgux-unix.

(print-region-new-buffer): Rename args to OSTART and OEND.

(lpr-headers-switches): New variable.
(print-region-1): Use it.

(lpr-add-options): New variable.
(print-region-1): Obey that.
