This site is about asking questions and receiving answers;
Each of the two have their own space to live in; there should be no question containing an answer nor an answer containing a question.
That's why Braiam removed your edit; your edit put informations deserveful to be contained in an answer in the question. That's not good because both the question and the answers need to be voted on, expecially the answers, because the top answers are going to be shown first. Therefore questions and answers need to be kept separate.
That doesn't mean that the effort you put in writing that edit is gone though; the revision history still contains it and you're free to answer your own question to add those details to the topic; quoting the Help Center:
###Can I answer my own question?
Can I answer my own question?
Yes! Stack Exchange has always explicitly encouraged users to answer their own questions. [...] you may go back and add an answer to your own question at any time.
Just copy-paste your edit into an answer. No one will mind about an answer that adds those details to the already existing answers; alternatively, you can add those details to one of the existing answers by editing it.
