Should diffWordsWithSpace treat consecutive new lines as a single "word"? #211

The behavior of diffWordsWithSpace surprised me with its treatment of consecutive new lines as a single word.

For example:

Left:

A

B

Right:

A
B

Given the above, I would expect this diff:

[{ value: "A\n" }, { value: "\n", removed: true }, { value: "B\n" }]

Instead, I get:

[{ value: "A" }, { value: "\n\n", removed: true}, { value: "\n", added: true}, { value: "B\n" }]

Is this the expected behavior? I would love if it was configurable, because it's A) surprising and, B) if trying to display the diffs visually, it makes changes to new lines seem more complicated than they really are.

(I can see about opening a pull request if a change to this behavior is welcome.)
