It is not just question of algorithm, even definition how should most
readable diff look like is problematic, for example when large block is
rewritten and one line is unchanged then you get diff like
if (x){
- foo
+ bar
} else {
- foo
+ bar
}
but it is better to create following diff as it does not break flow of code.
if (x) {
- foo
-} else {
- foo
+ bar
+} else {
+ bar
}
