True -- I think in the case of authoring technical documentation
at least, most authors would be a lot better off focusing on
trying to make their content accurate and precise, and less on
formatting niceties.

Thanks very much -- the following works like a charm. One
question: Is there a way I could modify it so that the filled box
extends all the way across the whole line length? (i.e., from the
left margin / page offset to the right margin).

Also, when I process a doc with this, it displays as expected but
I get a message saying "troff: automatically ending diversion `BX'
on exit." Is there some tweak I need to make to eliminate that?
