Comment:

 Looking at the database with xapian-inspect, it seems we manage to create
 a chunk for value 0 for document 2, and then a new chunk for value 0 for
 documents 1 and 3, which is wrong - we should be rewriting the existing
 chunk.

 Then when we look for value 0 for document 3, we look in the chunk for
 document 2 (since that's the largest chunk start <= 3) and don't find it.

 Needs fixing for 1.1.3.
