on branch reuse-subqueries
— Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows
a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide
a subquery number that is related back to the .selecttrace output.

on branch trunk
— Additional steps to help ensure that scalar subqueries are only evaluated
once even if they are used in multiple places within the query. This fixes
a performance regression reported on the mailing list and caused by
check-in [531eca6104e41e43] which was a fix for ticket
[787fa716be3a7f650c]. Think of this check-in as an improved fix for
that ticket.
