FYI, it has been committed;  I just need testing help:

    commit c155f654b4f755b4111bd9adb60559fe22526a10

        intarray:  return empty zero-dimensional array for an empty array

        Previously a one-dimensional empty array was returned, but its text
        representation matched a zero-dimensional array, and there is no way to
        dump/reload a one-dimensional empty array.

        BACKWARD INCOMPATIBILITY

        Per report from elein
