Currently the force flag in `git submodule add` takes care of possibly ignored files or when a name collision occurs. However there is another situation where submodule add comes in handy: When you already have a gitlink recorded, but no configuration was done (i.e. no .gitmodules file nor any entry in .git/config) and you want to generate these config entries. For this situation allow `git submodule add` to proceed if there is already a submodule at the given path in the index.
