El submodule git ya existe pero no?

Tengo git repo: https://github.com/bbialek/dotfiles Quiero crear un submodule para el plugin de patógeno de vim.

cd ~/dotfiles/vim git submodule add https://github.com/tpope/vim-pathogen .vim 

Dice:

'vim / .vim' ya existe en el índice

¿Es porque ya tengo submodules en ../dotfiles/vim/.vim/bundles/*?

Mis .gitmodules :

  [submodule "vim/.vim/bundle/nerdtree"] path = vim/.vim/bundle/nerdtree url = https://github.com/scrooloose/nerdtree [submodule "vim/.vim/bundle/vim-autoformat"] path = vim/.vim/bundle/vim-autoformat url = https://github.com/Chiel92/vim-autoformat [submodule "vim/.vim/bundle/vim-colors-solarized"] path = vim/.vim/bundle/vim-colors-solarized url = https://github.com/altercation/vim-colors-solarized [submodule "vim/.vim/bundle/vim-sensible"] path = vim/.vim/bundle/vim-sensible url = https://github.com/tpope/vim-sensible [submodule "vim/.vim/bundle/YouCompleteMe"] path = vim/.vim/bundle/YouCompleteMe url = https://github.com/Valloric/YouCompleteMe [submodule "tmux/.tmux/plugins/tpm"] path = tmux/.tmux/plugins/tpm url = https://github.com/tmux-plugins/tpm 

No puede registrar un submodule dentro de una ruta de submodule declarada (como vim/.vim/bundle/nerdtree )

Ya que tiene múltiples submodules que ya usan .vim , necesitaría usar una carpeta diferente para su repository de submodules .vim .
