Trying to do this would previously have the second one silently overwrite the first one's. We don't currently have this in lazygit, but I ran into the situation once during development, and it can lead to bugs that are hard to diagnose. Instead of holding a list of functions, we could also have added a panic in case the function was set already; this would have been good enough for the current state, and enough to catch mistakes early in the future. However, I decided to allow multiple controllers to attach these functions, because I can't see a reason not to.
