This example:-
.de a
\\$*
..
.nr b \w'Deri '
\Z@\*[a Deri]@
\h'\n[b]u'James
Produces:-
[derij@pip build (master)]$ groff -Tpdf -ww closing.trf | okular -
troff:closing.trf:5: warning: missing closing delimiter in zero-width output
escape sequence; expected character "@", got a newline
The closing "@" ends up in the output stream. I don't believe this has ever
worked properly in groff, but the warning may be new.
