Does that indeed give different output on your machine? I'm running git master, commit id 157ca12.

I agree with you that the "$var" syntax where var is an array is not very useful. At least I can't remember having used it with array variables. (I have for one-element variables, but your proposal won't change anything for those.) But I doubt your proposal will be that much of an improvement, once the "(command)" syntax is implemented. Are there any uses for it that are not covered by "(command)"?
