See attached exhibit files.

I run the following commands.


$ nroff -ms EXPERIMENTS/indented-display.ms >| id1.txt
$ nroff -ms -mwww EXPERIMENTS/indented-display.www.ms >| id2.txt
$ diff -u id[12].txt

The amount of display indentation should be relative to the existing
indentation, not absolute.

This may have something to do with ULS/ULE not being documented.

They got used in doc/webpage.ms nevertheless, which is how this discrepancy
came to my attention (when I tried to convert low-level .nf/.in/.fi mucking
about with idiomatic '.DS I'/.DE usage).
