Great!  (I thought your email was spam aat first because of the

That's exactly how we all learn the command line.

Right.  It turns out that a number of unix commands have this effect
of having trouble with a dash because that's used as a flag indicator.
So people added a feature to get around it.  Try this:

grep -- '-90 rotate' paper.ps

The '--' tells grep to ignore the '-' later on.

Also you could have used

grep '90 rotate' paper.ps

and that would show all cases.

You're welcome.

Apparently it's controllable in ps2pdf - note the other people pointed
out this flag:

But I agree - one should not have to turn this silly "smart" feature
off, it should be off by default.
