This is another reason why you should track important information in comments alongside the code instead of trusting VCS to preserve it in logs/commit messages, and to reject weird code missing comments from being merged. Not saying that fixes decades of cruft because you shouldn't change files without good reason and non-white space formatting is not a good reason, but I'm mentioning it because I've seen people naively belief bullshit like "code is self explanatory" and "the reason is in the commit message" Just comment your code folks, this becomes less of a problem
