To add to what @nhinkle and @random said, Gareth (the user who edited your post), is our most prolific editor in the last months. He has done some great work clarifying posts to help maintain the quality of the site.
In your case, it was just meant to help others to read the post more fluently. If you have any objections, feel free to revert to the first revision. Nobody will argue with that, since your post didn't lack formatting, proper spelling or capitalization. It's just a few minor touchups.
I hope you don't feel like this is a big deal upset or anything.
