Add minimal support for "o"-type print-file actions in lpd control files.

Browse Source 
This was described in the original RFC wrt lpr, but most lpr's do not
actually implement it.  There is some indication that MacOS 10.1 will
be using this when sending postscript files to print servers (that is
what "o"-type was supposed to signify -- postscript files).
