Difficult, but doable. Jan-Paul's sentence-level editing tool is able
to make the distinction. It would perhaps be possible to use that as a
framework for sentence-level diffs.
Difficult, but diff between versions of a page does it. Looking at diff
between pages, I simply thought firmly that only diff paragraphs were
stored, so that the page was built as updated diff segments. I had no idea
how this could be done, but all was "magic"!
