#3311: Mismatch between CLI and GUI for r.colors using external rules file
-------------------------+-------------------------
 Reporter:  madi         |      Owner:  grass-dev@…
     Type:  defect       |     Status:  new
 Priority:  normal       |  Milestone:  7.2.1
Component:  Raster       |    Version:  svn-trunk
 Keywords:  r.colors     |        CPU:  Unspecified
 Platform:  Unspecified  |
-------------------------+-------------------------
 There is a mismatch between the command line and the GUI of r.colors when
 providing an external file for color rules. Via command line the correct
 (working) command is:

 {{{
 r.colors map=map_name rules=rules.file
 }}}

 but via GUI, browsing the rules.file, it will build the following command:

 {{{
 r.colors map=map_name file=rules.file
 }}}

 throwing an error like:

 {{{
 Usage:
  r.colors [-rwlngae] [map=name[,name,...]] [file=name]
 [color=style]
    [raster=name] [raster_3d=name] [rules=name] [--help]
 [--verbose]
    [--quiet] [--ui]
 Flags:
   -r   Remove existing color table
   -w   Only write new color table if it does not already
 exist
   -l   List available rules then exit
   -n   Invert colors
   -g   Logarithmic scaling
   -a   Logarithmic-absolute scaling
   -e   Histogram equalization
 Parameters:
         map   Name of raster map(s)
        file   Input file with one map name per line
       color   Name of color table
               options:

      raster   Raster map from which to copy color table
   raster_3d   3D raster map from which to copy color table
       rules   Path to rules file
 ERROR: Options <map>, <file> and <-l> are mutually exclusive
 ERROR: At least one of the following options is required:
 <raster>, <raster_3d>, <color>, <rules>, <-r> and <-l>
