Subject: [PATCH 1/2] Fix thinko in tests for COPY options force_not_null and
 force_null.

Use COPY FROM for the negative tests that check that FORMAT text
cannot be used for these options, since if testing COPY TO,
which is invalid for these two options, we're testing two
invalid options at the same time, which doesn't seem intentional,
since the other tests seems to be testing invalid options one by one.

In passing, consistently use "stdin" for COPY FROM and "stdout" for COPY TO,
even though it has no effect on the tests per se, it seems
better to be consistent, to avoid confusion.
