Isn't this the stuff documented in groff's NEWS file?
Quoting under 1.18, Grotty:
SGR escape sequences are now used by default for underlining and bold
printing also, no longer using the backspace character trick. To revert
to the old behaviour, use the `-c' switch.
The same text also suggests how to make it work with less(1) and man(1),
and that the environment variable GROFF_NO_SGR reverts to the old way of
bolding and underlining (with ^H).
I assume some Linux distributions never did the necessary changes to man,
less and their setups to make this work. For what it's worth, Debian
Gnu/Linux (which I use) chose to disable the feature in groff instead:
Disable the new ANSI colour/bold/underline escapes in nroff mode, because
most pagers either fail to cope with it or need special options to do so.
