[PATCH 5/7] diff-highlight: test graphs with --color

From
Jeff King <peff@peff.net>

Our tests send git's output directly to files or pipes, so there will never be any color. Let's do at least one --color test to make sure that we can handle this case (which we currently can, but will be an easy thing to mess up when we touch the graph code in a future patch).

We'll just cover the --graph case, since this is much more complex than the earlier cases (i.e., if it manages to highlight, then the non-graph case definitely would).
