I agree that that multi-character (or even regex) delimiters would be
useful. Would it be reasonable for the copy process to differentiate
between single character delimiters which could be processed in
"high-speed" mode and multi-character or regex delimiters which would be
available as needed albeit at the expense of a performance hit?
