So we could still expose the parsetree of the current command.  I wonder
if it's already possible to get that from a C coded trigger, but I'll
admit I'm yet to code a trigger in C.  Will look into that.

Then as Andres proposed, a new function would be available to get the
value, we're not changing the trigger procedure function API in case the
language is C…
