Log Message:
-----------
Create a function quote_nullable(), which works the same as quote_literal()
except that it returns the string 'NULL', rather than a SQL null, when called
with a null argument.  This is often a much more useful behavior for
constructing dynamic queries.  Add more discussion to the documentation
about how to use these functions.
