DESCRIPTION

       --colors <color_spec> Configure color settings for console ouput.

              There are four faces to customize:
              +----------------+--------------+----------------+
              |  line prefix   |      +       |       -        |
              +----------------+--------------+----------------+
              | common segment |    added     |    removed     |
              | unique segment | refine-added | refine-removed |
              +----------------+--------------+----------------+

              The customization allows
              - to change the foreground or background color;
              - to set or unset the attributes 'bold', 'intense', 'underline';
              - to clear all attributes.

              Customization is done passing a color_spec argument.
              This flag may be provided multiple times.

              The syntax is the following:

              color_spec = face-name + ':' + attributes
              attributes = attribute
                         | attribute + ':' + attributes
              attribute  = ('foreground' | 'background') + ':' + color
                         | (<empty> | 'no') + font-flag
                         | 'none'
              font-flag  = 'italic'
                         | 'bold'
                         | 'intense'
                         | 'underline'
              color      = 'none'
                         | [0-255]
                         | [0-255] + ',' + [0-255] + ',' + [0-255]
                         | ('black', 'blue', 'green', 'red',
                            'cyan', 'magenta', 'yellow', 'white')

              For example, the color_spec

                  'refine-added:background:blue:bold'

              sets the color of unique added segments with
              a blue background, written with a bold font.

       --line-numbers  <compact|aligned> Display line numbers.  Style is optional.  When style = `compact', take
       as little width as possible.  When style = `aligned', align to tab stops (useful if tab is used  for  in‐
       dentation).  [default: compact]
