Interesting --- I know some languages allow trailing delimiters, like
Perl and Javascript. Could this mask query errors? Does any other
database accept this? Seems this would need to be done in many other
places, like UPDATE, but let's first decide if we want this.
FYI, it is usually better to discuss a feature before showing a patch.
