git submodule update --init --recursive stores gitdir in full path into .git of nested submodules. So, working directory is not portable to another directory.

On following example, Carthage/Checkouts/Quick/Externals/Nimble/ is nested submodule and Carthage/Checkouts/Quick/Externals/Nimble/.git contains full path.
