Thanks, Tadziu.  This may be what I've been looking for.  I'm not a
postscript expert, but this gives me something I can play around
with comfortably.  Will post back after I've tinkered a bit.

And yes, it only has to work for the postscript device since it's
easy enough to write an .if n condition in the case where a TTY
is being used (not very likely if a doc is formatted with the mom
macros, but conceivable).
