[RFC] git rm -u

Hello everyone,

I am thinking about implementing a feature but I would appreciate any feedback before I begin, because more experienced Git developers and users may see some major problem that I do not.

Earlier today I deleted a file from a repository. I deleted it normally, not by using `git rm`. So when I looked at `git status` on my terminal it told me about the file no longer being there. In my sleepy state of mind I ran `git rm -u` without thinking about. I did this because I have a habit of using `git add -u`. I know `git rm` does not support that option, but I tried it anyways without thinking about it.

When I came to my senses and realized that does not work I began to wonder if `git rm -u` should exist. If any deleted, tracked files are not part of the index to commit then `git rm -u` would add that change to the index. This would save users the effort of having to type out `git rm <filename>`, and could be useful when a user is deleting multiple files.

Does this sound like a reasonable, useful feature to Git? Or is there already a way to accomplish this which I have missed out of ignorance? Any thoughts and feedback would be greatly appreciated.
