Apparently I'm not alone in having trouble with ditroff.  Steve Hubert
(...ihnp4!uw-beaver!entropy!hubert) reports a similar problem, but with one
intriguing difference: his square roots are fine but the horizontal lines in
fractions (produced by deqn "over") are dashed!  Does this suggest anything
to anyone?
