> It is often helpful to have the batch level information when deep iterating a segment. Currently you have to run DumpLogSegments with and without deep iteration and then correlate the results. It would be simpler to print both. We could even nest the individual messages to make the batch boundaries clear. For example:
> {code}
> baseOffset: 0 lastOffset: 1 magic: 2 position: 0 ...
> - offset: 0 keysize: 5 ...
> - offset: 1 keysize: 5 ...
> baseOffset: 2 lastOffset: 4 magic: 2 position: 500 ...
> - offset: 2 keysize: 5 ...
> - offset: 3 keysize: 5 ...
> - offset: 4 keysize: 5 ...
> {code}
