EOF with pipes.

I'm sure that what you need here is not EOF's down pipes
but a *protocol*.  After all, EOF means that the other end
of the pipe has been closed, and not some other magical event.

I'm also sure that it wouldn't be very hard to break pipes too.
At least it'd be a step forward in the apparent quest to break
everything, that up till now worked in the stated way.

Exactly, it wouldn't be very compatible.  But I see that it's
already been done at RAND with that ridiculous eofp() junk.

I just dread the thought of "eofp() meets _filbuf()".
