I used find(1) here for debugging. The "make check-run" test
target needs to be updated to make stderr spew more obvious.
ok(run_script($cmd), '--skip-artnum -V1');
ok(run_script([qw(-mda --no-precheck)], $env, $rdr), 'deliver V1');
$mm = PublicInbox::Msgmap->new("$tmpdir/skip4");
- system "find $tmpdir/skip4 >&2";
$n = $mm->num_for($mid);
is($n, 13, 'V1 NNTP article numbers skipped via --skip-artnum');
}
