I have heard it said that the POSIX standard is maintained as a troff document (perhaps one of the authorities here can correct me). If that is the case, then even with hyphenation disabled, troff will break lines at "hard" hyphens, i.e., those appearing in the input, as in words like "mother-in-law". In the documentation of the forthcoming groff 1.23.0 release, we are more careful to say that the 'nh' request disables _automatic_ hyphenation. To prevent such hyphenation, it is necessary to use the hyphenation control escape sequence '\%' at the beginning of the word, as in "\%white-space". Regards, Branden
