Ah ha. Now we're talking. I think you'll find a lot to chew on there.
What I don't understand is how man(1) tells nroff/grotty what options to
use....
I recall that it's in a configuration file, e.g., under /etc (and that grotty's notion of what sequences to emit is not configurable beyond turning the feature on/off, in particular that it is unrelated to the terminal's capabilities).
