First, if the program isn't prepared to redisplay output anyway, no matter
whether or not you have job control it's going to scroll off the screen
anyway.  You don't gain much... Second, sometimes I will run a program, stop
it, cat a file, and then restart the first program and copy information from
the file I just catted.  Having the program redisplay the screen wouldn't
be quite the correct thing...

That's not a convincing argument to people who can't afford suns...

What are you arguing for? You say that BSD job control is a Bad Thing, and
that it is inferior to a window system.  Sure, I'd take a workstation without
job control over a terminal with job control, but so what?  Are you
saying that the UNIXes that run on windowing displays should have
job control taken out, because it is inelegant and un-UNIXish?  Or
are you just making fun of people who don't have suns?  So far your
arguments don't seem to have convinced many people...
