Okay.  You might consider just copying my latest pdfroff.sh, accompanying
pdfroff.1.man, and everything in my tmac/ subtree, *except* s.tmac, (which is
just a verbatim copy of yours, at the time I forked groff-pdfmark, and yours
has evolved since then), but I'll leave it to your discretion.

Oops! It looks like I copied, and pasted the wrong link; it should have been
[https://osdn.net/users/keith/pf/groff-pdfmark/scm/commits/69c99bee3ce93ddaae89026d61cea9bc75ecf453
commit #69c99bee]; (I should have noticed that the hash wasn't as I
expected).

Indeed.  That's the immediate parent of the intended commit.

Okay; I'll leave it with you.
