the issue. Had to give back a little performance, the optimization is still
a overall win.

invoked on a parameter that did not have multi-value IN processing enabled
via a prior call to sqlite3_vtab_in(). See

reduction and performance increase.

changed.

better gain, and code that is far less dodgy.

Perhaps there is a cleaner way to accomplish the same.
