Deleted Commit

What happened??? Why is our I: commit just gone!?!

Well, let's think about what happened during our rebase conflict resolution:

1. We started a rebase of banned onto main, meaning we're rewriting the
   history of banned to include all the changes from main.
2. We effectively removed all the changes from the I commit by choosing to keep the changes from main instead of banned.
3. We continued the rebase, and Git realized that the I commit was pointless, and because we're rewriting history anyway, it just removed it.

If our changes had been more complicated, say we had kept some of the changes from the I commit, and overwritten others, then Git would have kept the I commit in the history.
