OK. Comparing the last steps between this round and the previous one, I do think the separation of the responsibility among helpers is much more reasonable in this version, where: - submodule_embed_git_dir() is given a single path and is responsible for that submodule itself, which is done by calling submodule_embed_git_dir_for_path() on itself, and its sub-submodules, which is done by spawning the helper recursively with appropriate super-prefix; - submodule_embed_git_dir_for_path() computes where the given path needs to be moved to using the knowledge specific to the submodule subsystem, and asks relocate_gitdir() to perform the actual relocation; - relocate_gitdir() used to do quite a lot more, but now it is only about moving an existing .git directory elsewhere and pointing to the new location with .git file placed in the old location. I would have called the second helper submodule_embed_one_git_dir(), but that is a minor detail. Very nicely done.
