1cc093c2b5 Partial fix for a problem with LEFT OUTER JOIN. It used to be that the test 
for the right-hand table not matching the left table occurred after all
ON, USING, WHERE clause processing.  The test should occur after ON and
USING clauses are checked but before the WHERE clause is check.  This fix
works as long as the total number of "AND" separated terms in the ON, USING,
and WHERE clause does not exceed 32.  To do: make this work for any number
of terms and add test cases.
