This sounds like a good protection idea, but as it impacts existing backend code relying in sprintf's port version we should only do the assertion in HEAD in my opinion, and mention it in the release notes of the next major version at the time a patch in this area is applied. I guess that we had better backpatch the places using .*s though on back-branches.
