Yes, I like the confirm approach too. Since schmidj asked for a clarification and also did a feature request for a different wording than the well used "preserve" expression, there was room for some background. IMHO "preserve" works ok and it would only confuse things to change it.

But this is merely a side note to the real issue here, which could be a bug that schmidj is on to.
