Normally, psset just adds the duplex stuff to the PostScript
data, but sometimes the input file does not follow the Adobe
conventions, so "fixps" is called to clean up the mess -- and
that means ghostscript is asked to rewrite the file with its
"pswrite" device. We switch off this behaviour by default,
but for _real_ bad PS fixps does it anyway... :-(

(Maybe it's time to revert to our much simpler manual
PostScript "enhancing" procedure.)

BTW, are you sure your application produces good PostScript
all the time? Otherwise "fixps" wouldn't be needed...

What's happening here? This should be "lw|PS;r=..." -- did
you add the colon? (Although it shouldn't be too harmful
in this case...)
