* Let debug optionally target the status line (32 chars only) * Add batching of messages to debug ws comms * let Debug handle simple case of NaN would also close #1530 * Fixup debug tests for batch comms (no new tests yet) * mixup comms/api test to match new batch mode (no new tests) * Add test for NaN being sent OK. * redo original fix to padding / labels for new debug options * fix debug test (re-add fix from #1444) * Fix up merge issues in debug tests
