word-to-word highlight for multiple lines change

[dai-shi]

Hi, thanks for this nice library. I found something that is different from the GitHub style.
It's about word-to-word highlight (BTW, the README says char-to-char, which actually is word-to-word, isn't it)

If you have multiple lines changed, this doesn't work.
The example input is the following:

diff --git a/foo.js b/foo.js

---
+++
@@ -1,4 +1,5 @@
+zero
 one
-two word
-three word
+to word
+tree word
 four

It would be so nice if this is supported.

Hi @dai-shi,

BTW, the README says char-to-char, which actually is word-to-word, isn't it

I had some problems with the char-by-char implementation and since it was not very helpful for reading I started using John Resig implementation for word-by-word line diff and din't updated the README yet.
Will do as soon as I get to change it again.

Regarding the multiline block comparison,
Currently I don't have much time to work on this, but as soon as I can, I have some improvements in mind to do and block comparison is one of them.

I will look forward to it!

Another note is that the word delimiter seems spaces now, but it would be nice to delimit by some other characters like "()[];:.#@" and so on. I'm not sure how the delimiters should be defined.

@dai-shi if you have any ideas how to do this I would be glad to accept a pull request.

@dai-shi take a look at #7

And try it with diff2html-cli

I made diff in blocks and both char-by-char and word-by-word.

Any feedback?

[dai-shi]

Just did a quick test (not with the cli, but directly), it's awesome! So far working as expected.
