Good call, I'd forgotten about that.

There's almost certainly nothing wrong with his pager. man only sets -s
for its default pager, not for random stuff in the $PAGER variable
(which I had unset). I should add -s to the default $LESS set by man, I
think.
However, there is still a clear bug in eqn's output, forgetting about
the pager issues. I don't yet know whether it's a bug in the input or in
the output.

It's not quite as bad, but the matrix could easily be squeezed onto the
first page and isn't, so there's probably a spacing issue there, and the
brackets around the matrix are set too high.
