Subject: In the ANALYZE command implementation make statInit() a 2-value function
X-Git-Tag: version-3.8.1~131
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=59b08dd449760338d04d19f6f34847e9a92b1bd8;p=thirdparty%2Fsqlite.git

In the ANALYZE command implementation make statInit() a 2-value function
since the 3rd parameter was always the same constant.
