Among many other changes to doc/groff.texi, commit a8f804ff
(http://git.savannah.gnu.org/cgit/groff.git/commit/?id=a8f804ff) does this:
* (Sentences) Make clear that inter-sentence space is applied (if not
zero) when filling is enabled, not merely adjustment.
However, this doesn't appear to be true: a simple example shows groff applying
inter-sentence spacing to unfilled text:
.ss 12 144 \" make sentence space huge for easy visibility
Sentence one. Sentence two.
.br
.nf
Sentence one. Sentence two.
Branden, is this a misstatement, or do you think .ss *should* behave
differently in fill mode vs no-fill mode? There's no historical (pre-groff)
behavior in play here, since the second .ss parameter is a groff invention;
however, as far as I'm aware, groff has always applied the additional
inter-sentence space regardless of the fill mode setting.
