Follow-up Comment #2:

Thanks, Dave.

Yes, Bjarni's patch would indeed regress the documentation and make it
inaccurate.

I don't have a lengthy, boilerplate quotation from Dijkstra to patronizingly
offer.  Instead I'll have to settle for a concrete illustration.

Input:


$ cat EXPERIMENTS/backslash-d-and-r.roff 
A
.sp
B\v'1m'C\v'-0.5m'D
.sp 2v
E\dF\rG


troff output:

I trust the reader to generate PostScript from either of the above and further
confirm the difference in measurements by visual inspection.
