Yes, and I see it is actually used in many Tru64 manual
pages; since I want to be able to display such system pages
with Heirloom nroff, I should have code for it anyway.

Can you say in which pages you discovered them? I find much
fewer examples for .DS, without a characteristic pattern.
An examination of the CSRG archives shows that .Ds had been
defined in -mdoc as a "filled block display" in 4.3BSD-Reno,
but was deleted with 4.4BSD.
Which DocBook tag should correspond to .DS?

That is reassuring.
