So I can imagine that it would be neat in some contexts, but such a change would have much wider implications than options that tweak how a valid unified diff looks, or is generated. We'd need some way to mark a diff as "for ad-hoc viewing only". But as it sounds like you want this for git.git the Documentation/doc-diff script is much better than anything word-diff could spew out, as it diffs the resulting generated docs. I wonder (but haven't tried) whether you can't "diff" that using the same method that can be used to diff binary files using a custom driver. Hrm, except that in that case (with includes etc) there isn't really a 1=1 mapping between files within Documentation/ and generated docs (due to includes etc.). But I suppose it could be used only for those files that 1=1 correspond to the generated manpages.
