Most modern US typography uses the same amount of space for everything
on the line: between sentences, between words, and after any
punctuation that requires a following space.  (Here, "modern" refers
to the past 50 years or so; see
http://en.wikipedia.org/wiki/History_of_sentence_spacing#Movement_to_single_sentence_spacing)

So the default groff behavior of adding additional space between
sentences also does not follow today's typical US typography.  You
would have to specify ".ss 12 0" to achieve US convention.
