This causes a missing newline after "Application Version: 1" with cta_hdr10plus for an EDID I have. Any place that calls hex_block will have the same problem if it's possible for the length to be zero. In other words, a hex_block needs to have a linefeed even if it has zero length, because the caller assumes it will go to the next line as it does when the hex block is not zero length.
