OK. I'm almost at the point where I can start considering this merge request (not for the 1.0.11 release, but beyond that), however I won't be taking this thing in its single commit form, as it's just way too much in one go (and would result in plenty of merge conflicts with all other documentation modifications that I have been doing).

Instead, I'll be taking this piecemeal in a way that it won't interfere too much with the other stuff, so expect plenty of manual cherry-picking (with credit). Plus, it'll allow me to see what exactly was adjusted.
