Coloured --diff output

[selurvedu]

There is an option in diffutils:

--color [=when]

Specify whether to use color for distinguishing different contexts, like header, added or removed lines. when may be omitted, or one of:

• none Do not use color at all. This is the default when no --color option is specified.
• auto Use color only if standard output is a terminal.
• always Always use color.

Specifying --color and no when is equivalent to --color=auto.

It would be nice if Black had a similar option, probably with a different name.

Ugly hack (ideally Black should be able to output with colors out-of-the-box):

black --diff . | colordiff

@Peque yeah, I used that workaround before.
