git submodule remove?

Hello,

I recently encountered a situation where a user wanted to remove a submodule from a repository. Searching the mail archive, I found this thread [1], but it does not appear that it was ever followed up.

The Git Submodule Tutorial [2] has instructions for removing submodules, but it seems natural to teach git how to "submodule rm".

This change would require git-submodule.sh to:
    1. Modify the .gitmodules file (remove the entry for the submodule).
    2. Modify the .git/config file (remove the entry for the submodule).
    3. Delete the newly untracked files.

Another option to consider would be a "submodule rm --cached" option which would keep the newly untracked files. However, with this option, I believe it should still descend into the submodule directory to remove the leftover submodule ".git" folder.

Is there another way of doing this? If not, does this sound like a reasonable change?

Thanks, Tim Henigan
