	// The Go testing framework either uses os.Stdout directly or a buffer
	// depending on how the command is initially launched.  This results
	// in os.Stdout.Fd() sometimes being a Terminal, and other times not
	// being a Terminal which determines whether the ANSI library sends
	// escape sequences to colorize the text.
	//
	// The line below disables all colorization during testing so that the
	// git-bug command output is consistent in all test scenarios.
