I managed to redo the behaviour so this change was not necessary. However, I thought it was still not great to mix up display vs truncation, so I have moved this functionality into its own flag, --max-diff-block-lines-saved. This defaults to unlimited - I haven't run into problems with it myself, but people running this on low-end hardware could set it to something finite.
