Just one line of it.

```c
if (!dst->init_options) {
  git_repository_init_options dummy_options = GIT_REPOSITORY_INIT_OPTIONS_INIT;
  opts.flags = GIT_REPOSITORY_INIT_MKPATH;
  dst->init_options = /* allocate and check allocation */;
  memcpy(dst->init_options, &dummy_options, sizeof(git_repository_init_options);
}
```

If the caller wants a bare repo, they'll provide a valid `init_options` and set the proper flag. If they don't, they get the default options. The only hitch is that you'll have to track that allocation somehow, and free it later (maybe just a stack variable in `do_clone`?).
