If we have no data written to a key, dont add it, or its partition header.

        * camel-text-index.c (text_index_compress_nosync): If we have no
        data written to a key, dont add it, or its partition header.

2002-09-23  Not Zed  <NotZed@Ximian.com>

        * camel-block-file.c (sync_nolock): Mark root block dirty if we're
        going to sync it.
        (camel_key_file_finalise): de-count the active list if we close
        it.

        * camel-text-index.c (text_index_delete): Implement.
        (text_index_compress_nosync): Use index_delete when we're finished
        with the old one, so it is properly deactivated.

        * camel-index.c (camel_index_delete): Remove api call.  Mark index
        deleted in new state variable.
        (camel_index_*): Wrap all calls in check for deleted state.
