"But that list of links is the reason why ultimately I have decided to spend my time in a different editor."

Actually most of the functionalities I mentioned are available out-of-the-box. Ediff just works. Version control just works. I sent a long list of links so people could have a better idea how these features work. It's true, though, that emacs doesn't have everything out-of-the-box and you need to download and install and configure things, but the same is true for every single editor and IDE out there.
