I'm developing a diff program (not patch, but it can be extended). I'll mail
it to the list in one or two days.
However, I have some doubts about it. If I use a simple algorithm, sometimes
it reports many more differences than necessary. If I use a backtracking
algorithm, it should attain a maximum of matching lines, but with somewhat
big files it lasts forever. I wonder if it exits a fast and optimum
algorithm.
