Ahh. This answers the question--thank you!
Is there a publicly available source for DWB 2.0?

Thanks for the confirmation!

Hmm, intriguing! Do you know where I can get at this source? Is it in
Kirk McKusick's CD-ROMs?
I'm curious to know if it has:
1. the `lq` and `rq` string definitions; and/or
2. the following Eighth Edition macros documented in its man(7):
a. XE
b. 1C
c. 2C
(I finally got my printed original Eighth Edition manual out of storage
in Australia![2] Happy days for my historical research.)
