Using SGR doesn't automatically mean color support!  For example, to
have a bold letter A, grotty currently writes

  A^HA

(^H is <BACKSPACE>)

In SGR mode, this will be done as

  ^[[1mA^[[22m

(^[ is <ESC>)

The former works only with `less', the latter with e.g. `xterm' also.

Use `-P-c' as an additional groff option to not use SGR output.
