Word diff "ignores" newline and extra spaces about jsdiff

[matanox]

Could be nice adding this to the readme documentation..

Sounds like something I needed a while ago, and luckily I sent a PR (#22 :).

Try diffWordsWithSpace.

@papandreou don't WordDiff and WordWithSpaceDiff just use the same tokenization?
I must have missed something there when reviewing the source yesterday, and still am.

[papandreou]

Yeah, it's a little obscure. They use the same tokenization regexp, but WordDiff is based on a Diff instance where ignoreWhitespace is set to true, which WordWithSpaceDiff leaves out:

https://github.com/kpdecker/jsdiff/blob/master/diff.js#L155-L156

The Diff constructor sets it on the instance here: https://github.com/kpdecker/jsdiff/blob/master/diff.js#L41-L43

And uses it when deciding whether to consider two all whitespace fragments equal here: https://github.com/kpdecker/jsdiff/blob/master/diff.js#L137-L143

Oh thanks, I ended up switching to https://github.com/cubicdaiya/node-dtl, which lets me do my own tokenization without touching the code, but it's great to know this would also work!
