That's critical for Arch-1 style storage and for a lot of other things but maybeAgreed. Also it's crucial that the patch and diff used to build up the internal deltas used to store patches in the archive be perfect inverses of each other. E.g. using "diff -b" is not an option, even for files for which changes in whitespace is not significant. In other words, the compression of patches (based on diff) should be lossless.
there's more to the story, too. A common use for patching is to do merging. Maybe it is a mistake to insist that the way precise diffs are computed, inverted, composed, and applied is the only way merges get done. -t
