I have no immediate plans to work on this.  It would involve
messing around with the giant blast of *roff spew in
table::init_output().  The scope of the conditions seem a bit
broad.  Under the "nokeep" constraint, it might be possible to
warn only after ugly output has been emitted, but that's okay.
