If an important file is changed, we regenerate version.ent and so bump the revision. Otherwise, version.ent may be kept. Hack git-version.sh so we can ensure version.ent is really not changed. Add Makefile itself and git-version.sh into the important file list as they can definitely affect book rendering.
