If ReadUvarint reads at least 1 byte, it should convert any io.EOF encountered into an io.ErrUnexpectedEOF. Otherwise, the caller cannot distinguish whether the input was truncated or not.

The user could try and check whether the returned number was non-zero, but that doesn't work for a situation where the varint is denormalized zero.
