When building an ephemeral table of integers, do not assume that the table does not already contain N if the insert cursor points to N-1. Fix for ticket [61fe9745]. Also increase the version number to 3.18.2. This is the release candidate. (check-in: e1b71029 user: drh tags: branch-3.18)

The following SQL results in three rows of output instead of just two: 

CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT);
INSERT INTO t1(b) VALUES ('one'), ('two');
SELECT a FROM t1 WHERE a IN (1,2,1,2);

This bug was originally reported on the System.Data.SQLite mailing list. Bisect traces the problem back to check-in [925840cfdb] so that the problem was introduced in release 3.16.0.
