The `include` directive in `asciidoctor` documents doesn't seem to be usable at the moment for readme, it fails both when: - attempting to use the "raw" URL, probably due to [this](http://discuss.asciidoctor.org/Content-not-included-allow-uri-read-amp-unsafe-td1602.html) and/or a higher safety mode used. - attempting to use a relative path also fails (example [here](https://github.com/mikkoz/java8-quickstart-archetype/commit/95eb06624a84c69e71f3c0ba454c6b2f2089f88d) ). Is there any possibility of a workaround/fix?
