If you check ISBN numbers, instead of printing dates, you will
discover that there are (at least) two Red Books; one of them includes
the LaserWriter appendix, and the other doesn't. I have never seen a
version with a printer-specific appendix that wasn't about the
LaserWriter, but that doesn't mean they don't exist. 

In any case, the non-printer-specific Red Book does not include the
EOF information because it isn't part of the language specification,
but instead part of the implementation. If you want EOF indicated by
having the user spin around three times, bang a coffee cup on the
table, and shout "Vive Quebec", you are free to do so if you can
figure out how to detect it. As long as you do the right thing when it
happens, you are still speaking PostScript. Most printers take a
control-D as an EOF indicator; most emulators take that, or whatever
the OS they're on takes as EOF or whatever indicates to them that
their connection has been closed. 

As for Woody-bashing, it might be less prevalent if he was more often
correct and less often strident. For instance, if instead of answering every
question he only answered those he actually knows the correct answer to.
