I noticed an example in the Troff Reference Manual that looks strange
and I have no idea how it works.

In chapter 11, the following macro example was given to draw a line under
a string:

.de us
\\$1\l'|0\\(ul'
..

I understand everything except the "|0".  I assume it is the
N argument for the line drawing function, \l'Nc'.

It does work so it is not a typo in the manual.

I would appreciate any help on this strange syntax.  Please email a reply
since I do not read this newsgroup.

Thanks.
