Some anchor links produce a bad row in the pagelinks table (empty pl_title value) and the error "Invalid title in result set;" on Special:WantedPages.

Here is a simple test case. Create a wiki article containing these two lines:

#test

test

In the pagelinks table, you get:

mysql> select * from pagelinks where pl_title = '';
+---------+--------------+----------+

+---------+--------------+----------+

+---------+--------------+----------+
1 row in set (0.01 sec)

This happens in 1.14.0 but not in 1.13.2. In my 1.13.2 wiki, the pagelinks table has zero rows with an empty pl_title, so I assume this new behavior is a bug.
