Under certain (not quite easy to force, apparently) circumstances, a Git process that just warned about the deprecated config setting will spawn another Git process that then _also_ warns about that config setting. Let's try to tone that down by setting an environment variable that indicates that this process and all of its children no longer need to tell the user about this deprecation. Note: This patch does not help in situations where, say, scripts call Git multiple times and each of those times Git prints this deprecation notice. It is unclear whether we can do anything about this because those Git processes would have to signal to their _parent_ process that the advice was already provided.
