Fix a problem with the incremental blob API. sqlite3_blob_open() was always reading the data for the leftmost column of the row that the opened blob was stored in. If this column happened to contain a (the) large blob, sqlite would make a large memory allocation to read the data into. Which defeats the purpose of using incremental blobs. (CVS 5222)
