It's the awk that comes with MacOS X, which I think is a no-frills
BSD awk....

% awk -V
awk version 981019
%

Personally, I'd like to avoid extensions as much as possible to keep
things portable ("my" awk doesn't have gensub, for example), at least
until someone comes up with something better -- like making tbl do
this stuff for us. :-)

To that effect, here's a different approach to fixing tab(#) parsing:

I don't think so -- it's designed to work with groff, after all.
