I think 1 is impractical. I favor 2, and I have the feeling that groff's current behavior wasn't intended. I think the simple rule "if the word contains one or more occurrences of "\%", then hyphenation is allowed exclusively at these points" is easier to follow and remember. Here's another empirical observation: Suppose we have an "enquote" macro, .de QQ \(lq\\$*\(rq .. and we want to suppress hyphenation in the quoted word, then both .QQ \&\%antidisestablishmentarianism and .QQ antidisestablishmentarianism\&\% work, but the "\&" is needed in both cases. > reënable Nice! Like "coördinates".
