clean up the golden file a bit to have less meaningless content and be more robust to spurious diffs.
now there is output only for tests that produce output or failure.

these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.

(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)

the longs were rare enough that i don't think
it will cause integration problems.
