The sphinx-pre-install script will put out a verbose message recommending an upgrade for anybody running less than 2.4.4 - which was only released in March. So *everybody* will see that warning at this point. Let's only warn if the user is below our generally recommended version (1.7.9 currently). It might be good to put out a warning if people are explicitly making PDF files, but would need to be done in a different place and relatively few people do that.
