Log Message: ----------- Mention that .AT, .P, .SB, and .UC are extensions; it really matters because we only retain the language for backward compatibility in the first place. Part of the research done by <G dot Branden dot Robinson at gmail dot com>, see the list <groff at gnu dot org> for details. No change to the following conventions: Consider portable whatever made it into GNU troff no later than 4.4BSD. For portable extensions, mention their origin at the end of the description. For non-portable extensions, for example from man-ext, usually warn earlier, near the beginning of the description.
