Newbie question: how can I list added files?

git-ls-files doesn't seem to have an option for it,
neither does git-add.  Seems like it ought to be
trivial, but I'm not seeing how to do it.  :(  Thank you!!

P.S.:  yes, I know I can parse the output from git-status.
I'd really rather not for various reasons.  If it's the only
way, then I'll do the only thing.
