The loss of line-end by the lossy "word-diff" output does not matter if you never split hunks, but to be able to split a hunk at an in-between context line (which you can already do) and new features like per-line selection that are emerging, keeping 1:1 line correspondence between what is shown and what is applied is a must.

Unless you are volunteering to design (notice that I am not saying "implement") both diff generation/coloration side _and_ patch application side, that is. In which case, you may be able to come up with a magic ;-)
