git-blame -w: ignore whitespace

When refactoring code to split one iteration of a too deeply
nested loop into a separate function, it inevitably makes the
indentation levels shallower (that's the sole point of such a
refactoring).  With "git blame -w", you can ignore such
re-indentation and pass blame for such moved lines to the
parent.
