[Groff] New \D subcommands

[Werner LEMBERG]

>From NEWS:

  o In groff versions 1.18 and 1.18.1, \D'f ...' didn't move the
    current point horizontally.  Despite of being silly, this change
    has been reverted for backwards compatibility.  Consequently, the
    intermediate output command `Df' also moves the position
    horizontally again.

    \D'f ...' is deprecated since it depends on the horizontal
    resolution of the output device (given with the `hor' parameter in
    the DESC file).  Use the new \D'Fg ...' instead.

  o For orthogonality, new \D subcommands to change the fill color are
    available:

      \D'Fr ...' (rgb)
      \D'Fc ...' (cmy)
      \D'Fg ...' (gray)
      \D'Fk ...' (cmyk)
      \D'Fd'     (default color)

    The arguments are the same as with the `defcolor' request.  The
    current position is *not* changed.

Enjoy!
