Use diffs if provided, otherwise compute it ourselves.
There are four ways to call this function, depending on what data is
available to the caller:
Method 1:
a = text1, b = text2
Method 2:
a = diffs
Method 3 (optimal):
a = text1, b = diffs
Method 4 (deprecated, use method 3):
a = text1, b = text2, c = diffs
