I agree that these warnings are unwanted when you run "checkout ."
in a repository with tons of i-t-a paths (but on the other hand,
having tons of i-t-a paths is unusual so the user might want to be
reminded of them--I dunno).

With or without the new warning(), this one looks an improvement
over the previous one to me.

Thanks.
