I think we should try and change the auto-detection of the coding-system, so as to keep track of the reason for the choice (where possible), and then offer a command that uses this info to explain what happened (e.g. "inhibit-nul-byte-detection set and found a NUL char at position "). For extra bonus points we could change some major modes (e.g. prog-mode and text-mode) to automatically warn the user when the buffer is in unibyte mode and suggest running that new command.
