No, I'm subsuming your comparison. I don't want more space with A than with B; that was what I was complaining about with WordStar, which didn't know the difference between the "St." in "St. Louis" and the " or ! that might end a sentence, and spaced accordingly.

And it doesn't seem to me that Word does this. If I want extra space after a sentence, I have to type two spaces. Which is why my point was that I get more space with C (or D) than with A (or B).
