show-branch: color the commit status signs
Make it possible to color the status character ('*' '!' '+' '-') of each commit corresponding to the branch it's in. This makes it easier to follow a particular branch, especially if there are larger gaps in the output. Add the config option color.showbranch and the command line options --color and --no-color to control the colored output.
