We are only tightening with this patch, and we were passing any random things through with the original code anyway, so without [PATCH 3/3], this step must be making it only better, but I have to wonder one thing. You keep saying "get prompted" but are we sure we always stop and ask (and preferrably---fail and abort when the end user is not available at the terminal to interact) when we have such a questionable address?
