This tiny patch correct a failure in test_tempfile on Windows: in
SpooledTemporaryFile, avoid translating the newlines twice.
Otherwise, in "universal" text mode, \n gets transformed to \r\n, then
to \r\r\n, which is read as \n\n.
Passing the encoding is OK, since the round-trip gives the same result,
and it allow encoding errors to occur at the right place.
