I meant, instead of:

  git_config(git_fetch_config, NULL);

which updates a series of config settings, something which loads
_in_the_code_ just the one value for 'core.submodulesFile' previously
set either via "git -c" or "git config".

It turns out what I was looking for is git_config_get_string_const().

The new patch will be simply this:

diff --git a/config.c b/config.c
index 6ffb1d501..1ef9801d3 100644
--- a/config.c
+++ b/config.c
@@ -2087,6 +2087,7 @@ int git_config_get_pathname(const char *key, const char **dest)
  */
 void config_from_gitmodules(config_fn_t fn, void *data)
 {
+       git_config_get_string_const("core.submodulesFile", &submodules_file);
        if (the_repository->worktree) {
                char *file = repo_worktree_path(the_repository, submodules_file);
                git_config_from_file(fn, file, data);


Which covers my use case without changing the fetch behavior for previous
users, as "core.submodulesFile" is a new option.

Thanks,
   Antonio
