-

  ```
  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 indentation). \[default: compact\]
