I have applied all your patches but have one question. Consider the
following sample manual page, which uses the .TP subsubsectioning technique
you have recommended. In the sample, observe the difference between
subsubsections 1a and 1b.
FOO(7) Linux Programmer's Manual FOO(7)
NAME
foo - sample to illustrate manual-page markup
DESCRIPTION
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
Subsection 1
Sed at ante.
Subsubsection 1a
Mauris eleifend, quam a vulputate dictum, massa quam
dapibus leo, eget vulputate orci purus ut lorem. In
fringilla mi in ligula.
Sss 1b Pellentesque aliquam quam vel dolor. Nunc adipiscing.
Sed quam odio, tempus ac, aliquam molestie, varius ac,
tellus.
Subsubsection 1c
Vestibulum ut nulla aliquam risus rutrum interdum. Pel‐
lentesque lorem. Curabitur sit amet erat quis risus feu‐
giat viverra.
Subsection 2
Pellentesque augue justo, sagittis et, lacinia at.
CONFORMING TO

Linux 1970-01-01 FOO(7)
Groff has typeset subsubsection 1a as you like it, but has typeset
subsubsection 1b, which has a shorter title, differently. This is okay
with me, but is it okay with you?
Hmm, you're right. I knew the difference but didn't think of it in that
case.
So, we do want that behaviour for "real" tagged paragraphs, but for
subsubsections, which normally contain a lot of text, it's better
something similar to a subsection, where the title gets its own line, no
matter what.
There's a page that does that: system_data_types(7). I didn't recommend
it to you, because in the inner .TP we don't want that. But in the
outer ones we actually do, so we could use a mix.
A more sensible approach would then be this one:

In this case we have line breaks after subsubsections, but not after
normal tagged paragraphs.
If you don't have much time, I can fix it and send you the patch.
Thanks!
