Eh, the version_code parameter is supposed to be used to report the
backends version code, right?

The backend should not check the version present in the buffer, it
should store it's own version into the buffer.

If a frontend calls multiple backends using the same buffer, one
backends might get confused if the previous gave a different version
number.

The backend version number is unrelated to the sane distribution
version number.
