Right, a symbol for the __overlay__ node itself of a root-targeted
fragment would come out empty instead of "/". The next revision keeps
the target path when the tail is empty:

	if (target_path_len == 1 && target_path[0] == '/' && path_tail_len)
		target_path_len = 0;

The other two findings are pre-existing and tracked in the cover
letter's open items.
