First, this need some grammar cleanup. But more importantly, it's not
quite a correct formulation. CSV mode splits a line on (unquoted)
delimiters. Within each chunk dequoting is done, and withing quoted
sections de-escaping is done. But nothing is discarded.

i.e. with the quote char as '"', 'foo"bar"baz' becomes 'foobarbaz' and '
"x" ' becomes ' x '.

I understand Dary's problem has been that Oracle pads CSV lines with
spaces. Perhaps we need to warn specifically about that - I suspect most
people for whom it might be important will miss the significance otherwise.

I'll work on some better wording.

cheers
