/**
* Page moving and page protection (and possibly other things) creates null
* revisions. These revisions re-use the previous text already stored in
* the database. Those however do not trigger re-parsing of the page and
* thus the ready tag is not updated. This watches for new revisions,
* checks if they reuse existing text, checks whether the parent version
* is the latest version and has a ready tag. If that is the case,
* also adds a ready tag for the new revision (which is safe, because
* the text hasn't changed). The interface will say that there has been
* a change, but shows no change in the content. This lets the user to
* update the translation pages in the case, the non-text changes affect
* the rendering of translation pages. I'm not aware of any such cases
* at the moment.
