Suggestion: git status --untracked

I find myself wanting sometimes to filter out the output of git-status, to feed it to another command (for example, git-add, or rm, or cat >> .gitignore). However it's not currently very easy to parse in a one-liner.

I'm suggesting to add options to control this behaviour. My suggestion would be (for a start) to add an option --untracked that will list all untracked files on stdout, without a leading "#\t", and without listing the added / modified / removed files.

I'm willing to implement it, but I'd like to have some discussion about the interface first. Is that a good idea at all, and how could it be improved interface-wise?
