Doesn't seem practical, as the actual error may not occur till much
later, far away from the COPY code itself.

We have to change *something*, Bruce, because as things stand it's
completely ambiguous whether a \r is a legitimate data character or
something introduced by a newline conversion.  If you insist on 100%
backwards compatibility then we'll be fighting this problem forever.
(Or at least till Windows dies ... yeah right.)

Please note also that \ r (two characters) is *already* accepted as
meaning a carriage return.  Ditto \ 0 1 5.  So it's quite possible
that applications generating COPY data may be using one of these
representations and not be affected in the slightest.
