It seems that what broke is that if output of indent -troff was to be passed in
a troff -mindent command line. meaning that there use to be a indent.tmac
somewhere but neither groff, neither heirloom roff seems to be providing it at
all a indent.tmac or equivalent.

So I doubt it ever worked on FreeBSD. I can see online some documentation
speaking about (on oracle website) and even some crazy french website saying it
worked with groff, but can't find the file in groff history either
