Excellent sleuth work, Ralph! (As always) Thanks! However, I was more curious about what it was an abbreviation for, believing it was "recently" added (with "recent addition" meaning anything added to Groff's codebase within the last 10 years).
Given Roff's longevity, it becomes easy to forget how old Groff is too (well, to a 30-year old...)
