(As suggested by Hans Bezemer in
http://lists.gnu.org/r/groff/2025-03/msg00000.html)
The back bond is created of spaced lines.
With a slight alteration this can be converted into
a dashed triangle / wedge.
Although the several textbooks / websites I consulted use different back
bonds
(some dashed and tapered, some just a single dotted bond),
the dashed wedge seems the most common.
(Patch attached rather than inlined, as it contains tabs, which savannah does
not render well even in verbatim blocks:
