I'm currently trying to determine when an issue was fixed in a long list of commits. I attempted to do this by running `git bisect` and marking the commit where I knew it was broken as bad, and the tip as good, but I got back an error message saying that good revs weren't ancestors of bad ones. I'm currently working around this by mentally reversing the meanings of good and bad, but it feels unnatural and error prone to have to say `good` when I encounter the failure and `bad` when i don't. Couldn't git simply do the same thing and internally reverse the meaning of good and bad if the bad revision is an ancestor of the good?
