Bug Description

Our docs for innodb_use_sys_stats_table contain the following statement: "Note: This option may cause less frequent updating of statistics. So, you should intentionally use the ANALYZE TABLE command more often."

I've checked the code and verified that the actual behavior is to never update statistics unless an explicit ANALYZE TABLE is issued. And that's intentional, according to Yasufumi.

So the docs should be updated to reflect that.
