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.
