Hamano, I could not make this decision like what you said between "'--empty' is a synonym to '--empty=die'" and "'--empty' alone is an error". In my opinion, it is a little wired that '--empty' should not act as "died" semantically. Reversely, it may be better to support a synonym between '--quiet' and '--empty=skip'.

I will squash the commit into the previous one later and hope all participants and reviewers make a decision.
