Subject: [PATCH] Put cursor on root when closing bookmark table

If the cursor is not already positioned on a node when the bookmark
table is closed, then the resulting position of the cursor is not
determined.  Here, we default to positioning the cursor on the
root when the bookmark table is closed.
