I agree with the "unbuffered" statement. I am surprised that you expect fflush()
to do nothing in that situation... but I am no expert in that area. Can you
point me to some documentation?

In any way, would all this be a problem here? The worst that could happen would
be that the user would not see the message, right?

Are you aware of stderr usage in Git that could cause more trouble?
