[A few "strace -f -e execve"s later...] Hmm, for the man-db man(1) in Debian bullseye (testing), at least, this is true! And checking its own man page, it looks like it was true as far back as April 2001 (the horizon of its Git history). I guess there are so many man pages that embed tables without including the hint that the man-db maintainers decided not to leave the comment to chance. The only other man-like program I know if in anything like wide use on Linux systems is mandoc, which does all its own parsing and doesn't depend on a *roff at all. Retaining an accurate comment would be a kindness to other man implementations I'm not aware of and to weirdos like me who run groff directly because we develop it (though admittedly, even for us, there is the crutch of grog(1)). But I'll grant--these populations may be small. > See my comments above.
