Why does 'submodule add' stage the relevant portions?

Hi,

I find this behavior very inconsistent and annoying. Why would I want to commit the submodule change immediately? Maybe I want to batch it up with other changes and stage it at a later time. Why should I have to unstage them manually now? I get the other side of the argument: what if the user commits the .gitmodule change at a different time from the file change? In other words, the user should have a way of saying 'submodule stage' and 'submodule unstage'.

Now, for the implementation. Do we have existing infrastructure to stage a hunk non-interactively? (The ability to select a hunk to stage/ unstage programmatically). If not, it might be quite a non-trivial thing to write.

Git 2.0 is coming soon, so I'm excited about breaking a lot of backward compatibility ;)

Thanks.
