I see what you meant, then.  Sorry for being a bit slow.  Now that I think
about it, it may be possible to make char-level diffs on words reasonably
fast, by running char-level diff only once (rather than once per word),
basically putting all the words-to-diff into two files, separated by
sufficiently large and unique text to make sure that diff won't get
