Undefined behaviour can change without notice, and users should be strongly discouraged from using it. Describing what the current implementation happens to do moves us exactly in the opposite direction. `--follow` is a checkbox feature. You can use it "only with a single filename on a linear history" or all bets are off otherwise. That is what we should describe if we want to be honest.
