+ * sql/expressions.lisp:
+
+ Fixed bugs related to outputting where clauses in delete/updates
+ using sql syntax. Previously subselects and where clauses without
+ data (such as an empty or clause or and clause) would cause
+ failures.

+ * sql/operations.lisp
+
+ Fixed bug reported by JTK related to the not-null sql-expression
+ especially as used in conjunction with the is operator.
+
+ Made null called with more than one argument throw an exception
+ instead of silently discarding all arguments past the first
