[Orgmode] Patch: correction for tree-style sitemap (org-publish)

[Sebastian Rose]

Issue
=====

Sitemap not correct, when mutlitple subdirectories (my fault I
believe, sorry). Only the tree-style sitemap is affected.


How to reproduce
================

Try to export the following structure to HTML (directories
marked by `/'):

base-directory/
            |
            +-- B/
            |   |
            |   +---C/
            |   |   |
            |   |   +--- c.org
            |   |
            |   +---D/
            |       |
            |       +--- d.org
            |
            +-- E/

The resulting sitemap:


- B
  - C
    - c.org
- B              <= B again!
  -D
    - d.org
- E

Should be:

- B
  -C
    - c.org
  -D
    - d.org
- E
