I forgot whether I reported my solution, and if I did, I do not see my answer here, so here it is for the record. The culprit is: /usr/share/groff/site-tmac/man.local which has the following: . \" Debian: Disable the use of SGR (ANSI colour) escape sequences by . \" grotty. . if '\V[GROFF_SGR]'' \ . output x X tty: sgr 0 This means that one must /set/ rather than unset GROFF_SGR to restore the normal nroff behavior.
