To achieve the best, we have to find the pairs of lines (one minus and
one plus for each pair) which most match each other, and then do the
word diff for each pair.

Wouldn't be enough to treat run of plus/minus lines as a single block,
tokenize, do token-based (as opposed to line-based) diff, then show it
using linebreaks of the destination file (pluses line)?

I tried the "using linebreaks" but I discarded it because I did not think
it would work.  If we rewrite the last three lines above with this single
line:

Wouldn't be enough to use magic?

and apply that algorithm between the two, then we would get a long single
line that has words painted in red, two lines worth, followed by green "to
use magic?"  and finally an end-of-line.
