IE8 issue with split

[stockholmux]

Hi-
In my recent project I noticed that, while the code executed in IE8, the resulting string from JsDiff.applyPatch was scrambled. I was able to work around the issue by using Steven Levithan's polyfill for split ( http://blog.stevenlevithan.com/archives/cross-browser-split ). The way the variable 'meh' in applyPatch is being used isn't supported in IE8. I wouldn't use the polyfill in all situations as it seems to be slower in some cases.

@stockholmux do you have examples of the failure? Do you still see it under the latest with #24 integrated?
