Should be 2020 now. Will fix that up.

I still dislike the handling here. Any caller can simply do a
expect_pgm_int();
test_one_sccb(...)
check_pgm_int_code(PGM_);
Same thing goes for exp_rc. We really should drop exp_rc and exp_pgm
handling from the function completely and handle it in the caller. That
makes the tests actually readable.
But I feel like I am repeating myself. I'll queue this patch with the
2020 fixed up and might send a fixup myself (if I find some spare minutes).
