Since I'm not a user of -ms I wanted feedback from the list which I
didn't get (probably my mail has been missed by some of you).  I'm
repeating my mail from February below -- perhaps this time I get a
reaction from the groff audience :-)

Hmm, what about the following instead:

+++ s.tmac      Wed Feb 26 17:58:58 2003

 .de @nop
 .de @init PO \\n(.o
+.if !rPO .nr PO \\n(.o
 .\" a non-empty environment
 .ev ne

This has the advantage that \n[PO] can be set on the command line too,
and you no longer need to use .po directly (which is quite irritating

Larry, looking into s.tmac, I see some variables like FPS and FVS (to
set the footnote size and vertical spacing) which can be set on the
command line but which aren't documented at all.  Can you fix that in
both and groff.texinfo?  [Look for `if !r' and `if !d' in
s.tmac to find the relevant spots.]
