Let me tell you a fun little story about this time Aaron tried to tell me I deleted some important info from a GitHub issue when I edited it. I was pretty sure I didn't, but anything is possible.
Thankfully, GitHub keeps revision history of all comment edits. You can click on each edit and see the content from that point in time. This makes sense since revision history is what GitHub is all about. It was fun for me to watch Aaron grumble and admit he was wrong. (Only happens like once a year, I have to enjoy it.)
Here's what it looks like:
Pretty handy feature!
