Subject: [PATCH] Fix language index for document in sub directories

The previous version did not care the case where documents are placed
in any sub directories. It assumes all documents are placed
in the top doc directory.

We now have atc-stats/***.html and the previous build script
does not work for these pages.

This commit fixes the problem.
