Re: [Groff] Letterspacing

[Doug McIlroy]

Neither column of the side-by-side display looks very
good to me. The normal-spacing column is definitely
thin. The reduced-spaceing column is patchy--thick
in places and thin (by comparison) in others. I
prefer unjustified text to either. Besides having
more uniform density, it offers landmarks--the
profile of the right margin--to help the eye
maintain vertical focus. Justification of narrow
columns is a kind of circus trick, like that of
the dog in Dr. Johnson's famous quip. [Google
Johnson "hinder legs"]
