[51f4fcaa] part of check-in [7153552b] 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. (check-in: [7153552b] user: drh branch: reuse-subqueries, size: 7025)
