ok by me, though for clarity I would phrase this:

> +		i += s->tree != s->root;  /* account for ".." entry */

as follows:
		if (s->tree != s->root)
			i++;

Your code is not incorrect, but I would rather avoid clever C tricks
like this. They can make the code harder to read for people who
are still learning C.
