Yuck.

That would still be annoying to some people and outright buggy to others, if their workflow relies on HEAD (e.g. compare with HEAD while reviewing the log messsage) and then now they instead need to adjust (e.g. compare with the index instead). Perhaps you are one of them (apparently I am not, as I did not notice the behaviour change until you pointed it out here).
