Me neither. I know them under the (probably vaguely incorrect) name "ANSI
escape sequences".

The -c option mentioned is an option to grotty, so you have to "tunnel" it
through groff's -P option. This works for me (with groff 1.19):

   groff -P-c -Tlatin1 -man [...]

(To confuse things a bit, groff has a -c option which is documented to
disable tty color output, which in turn requires SGR -- but it disables
color and nothing more.)

Alternatively, you may set the GROFF_NO_SGR shell environment variable.
That's also mentioned in grotty(1).
