The previous fix for ticket [d85fffd6ffe856092ed8da] in check-in [0a514e62ad1ebe5c12da8dae] did not completely address the probably in that it only worked for cases where the OP_SCopy that loaded the register was the last instruction in the sequence for the expression, which is not necessarily the case for expressions like CASE...END.

13:07
Enhance the CLI to render EXPLAIN QUERY PLAN using an ASCII-art graph. This works with ".eqp" modes and when the query begins with exactly "EXPLAIN QUERY PLAN".
