           Summary: Web Inspector: use jsdifflib for revision diff
                    calculation.
           Product: WebKit

          Platform: All

Present diff calculation is incomplete, it does not properly handle the following case:
    [a, b, c, d, e, f, g, h] => [c, d, e, f, g, h, a, b]

It detects [a, b] as the lcs.

I imported jsdifflib from https://github.com/cemerick/jsdifflib. It has BSD license that is compatible with WebKit.
