In the examples "webpack/examples/multiple-commons-chunks/", the current config in webpack.config.js has one spelling mistake, as seen below:

    new CommonsChunkPlugin({
        name: "admin-commons",
        chunks: ["adminPageA", "adminPageB"]
    }),
    new CommonsChunkPlugin({
        name: "commons",
        chunks: ["pageA", "pageB", "admin-commons.js"],
        minChunks: 2
    }),
    new CommonsChunkPlugin({
        name: "c-commons",
        chunks: ["pageC", "adminPageC"]
    }),

we should change "admin-commons.js" to "admin-commons" in the second CommonsChunkPlugin option,

if it is "admin-commons.js", the bundle named "admin-commons" will contain two module, "./modules/admin" and "./modules/a-b-c";

but if it is "admin-commons", the bundle named "admin-commons" will just contain one module -- "./modules/admin".

This lead to a entirely different result , which take me about two days to understand the way how webpack bundles commons chunk..So please correct it~~~thanks
