 Replying to [comment:20 cmbarton]:

 > A flag (-ui) can be added to any module to ensure it launches a GUI, but
 is only necessary for a few modules. AFAICT, this behavior is not
 documented anywhere (run g.region help or look in the manual for GRASS). I
 tend to think that 'secret' behavior of any interface element is not a
 good idea from the user perspective--even if the secret is inadvertent and
 logical from other perspectives.

 the attached patch attachment:force_gui.diff adds '--ui' to the help
 printed by the parser (see example below). I agree that this switch is not
 documented well, even it's not noted in the `g.parser`'s help page.

  Displays user-specified raster map in the active graphics frame.

  display, graphics, raster

  d.rast [-ni] map=name [values=value[-value][,value[-value],...]]
    [bgcolor=color] [--verbose] [--quiet] [--ui]

   -n   Make null cells opaque
   -i   Invert value list
  --v   Verbose module output
  --q   Quiet module output
  --ui  Force GUI dialog to come up

       map   Name of raster map to be displayed
    values   List of categories or values to be displayed
   bgcolor   Background color (for null)
              Either a standard color name or R:G:B triplet
             default: white
