Attached is a revised patch. I didn't see anything major that needed to
be corrected, but there were some minor cleanups to be made. I also
clarified the error message when a CONTINUE is specified outside a loop
(although I wasn't quite sure what error message to use: SYNTAX_ERROR
seems a bit weird, as the problem isn't detected until the end of the
function's execution. I'm using PLPGSQL_ERROR at the moment, but
suggestions for a better choice are welcome).

Barring any objections, I'll apply this tomorrow.
