[Groff] Underlining in groff

[Blake McBride]

Greetings,

I know about troff using italics, and nroff using underlines, but I want to
do underlines in groff (troff mode) too.  I searched the net and found the
ul.tmac (by Werner LEMBERG, version 1.0, 12/18/03).  It partially works but
not well enough for me.

See:  http://osdir.com/ml/printing.groff.general/2003-12/msg00079.html

If I do:

    .so ul.tmac
    Some text
    .Underline "Executive Summary"
    and some more text


it works fine.  However if I do:

    .so ul.tmac
    .ce 1
    .Underline "Executive Summary"

It correctly centers the text but the entire line is underlined instead of
just the "Executive Summary".

Also if I do:

    .so ul.tmac
    .ce 1
    .Underline "Executive Summary"
    and some more text

An underline starts at the "E" and ends on the middle of the next line.

How can this be easily done?

Thanks.
