    ps2write - don't password encrypt PostScript output!
    
    Noticed while testing the args commit; if we set -sOwnerPassword (to
    create a password-protected PDF file), but select (e)ps2write as the
    device, then the resulting PostScript file would have all the streams
    (in a PDF sense) encrypted with PDF password encryption.
    
    Unsurprisingly, this result in a completely unusable PostScript file.
    Lets not permit that....
