Uh, git-archive?

I was thinking that -z could conflict with other uses for in/output, but indeed git-archive does not seem to have any other area that would be affected by -z.

So this request at the current point of time can be reduced to let git-archive have --stdin and -z options. That is actually important as one can't concatenate zip-files, and so xargs does not help.

But file lists are also important for things like git-diff (for which the NUL-endedness of input is a separate issue from its output). So instead of adding stdin piecemeal, it was some sort of idea to have this generally available in file lists.

If somebody can come up with a nice syntax.
