I think the primary part of coloring i.e. "white is common, green is added, red is removed" together with "bold is new, dimmed is old" is quite usable and not broken. The non-coloring part, like patch matching and driving diff over a pair of "git show" output, looked reasonably solid when I read it (even though I admit I did not audit for leaks). The only thing I think we would be better off without is the coloring of whitespace errors (at least in the current shape). I cannot shake the feeling that temporarily setting core.whitespace to nothing (i.e. we do not detect any whitespace errors and hence we do not show any) while running diff-of-diff may be a workaround that is less damaging to the code base than piling band-aid on the codepath that is shared with plain diff (not diff-of-diff).
