Coloring matches makes them easier to spot in the output. Add two options and two parameters: color.grep (to turn coloring on or off), color.grep.match (to set the color of matches), --color and --no-color (to turn coloring on or off, respectively). The output of external greps is not changed. This patch is based on earlier ones by Nguyễn Thái Ngọc Duy and Thiago Alves.
