Attached is a patch that errors for \r and \n in delimiter and null. I
kept the ERRCODE_FEATURE_NOT_SUPPORTED error code because that is what
all the other error tests use in the copy code in that area. I did
nothing with backslash.
FYI, David, my email reader is having problems reading your emails

Content-Type: text/plain; charset=iso_8859_1
My understanding is this should be iso-8859-1, with dashes.
