I fixed the underline problem with a fairly trivial post filter program.
I think that the col filter is a far more complex problem.  If you want
to do multiple columns, or use the {T constuct in tables (both generate
reverse line feeds), you will need a col filter that recognizes the special
sequences that nroff genrates for your printer, and it will need to look
at the -T table to determine how much space each character uses on paper.
Have fun!  Personally, I just avoid these. :-)
