You wouldn't even need to bump the version number. Adding a header is
forward-compatible. Either it is present (future code), or it isn't (old
code, or future code but not applicable).

Things like copy-from information, and Branko's prev-node-path, can be
omitted from the "headers" in a compatible fashion.
