0143e48568 fix for bug #1724 'WHERE ... IN() optimizer behaviour
has changed since 4.0.14'
We need to calculate cost of RANGE
scan if it is present instead of cost of 
FULL scan.

dd2012067e A fix for the bug in a SELECT with joined tables with ORDER BY and
LIMIT clause when filesort had to be used.

In that case LIMIT was applied to filesort of one of the tables, 
although it could not be.

This fix solved problems with LEFT JOIN too...

3c1a311348 SCRUM Task 430: Allowing braces in joins by simply removing them.
Fixed the remaining join variations, (left, right, natural, etc).
(Previous fix only solved "," and "[cross] join".)

8bd61c3fce Task 430: Allowing braces in joins by simply removing them.
This is a simple fix, allowing a join_table_list in the right reduction of a
normal_join sequence, instead of just a join_table. This makes things like
"t1, (t2 left join t3)" work, but it also allows "join" and "cross join" instead
of ",".

This should fix the bug reported as:
