Max Reitz fa27c47810 doc: Preallocation does not require writing zeroes ... When preallocating an encrypted qcow2 image, it just lets the protocol driver write data and then does not mark the clusters as zero. Therefore, reading this image will yield effectively random data. As such, we have not fulfilled the promise of always writing zeroes when preallocating an image in a while. It seems that nobody has really cared, so change the documentation to conform to qemu's actual behavior.
