Correct.

If I call this command, a zero-size file called 'dum.dum' gets
created, together with a log file called 'luatex-basics.log' (attached).

Luigi, I consider it strange that the log file has this name, given
that the input file on the command line is `openout.tex`.  If I remove
the `--fmt` option in the above call, I get the expected `openout.log`
file.  Is this a bug?

For reference, here is the contents of `openout.tex`.

```
\newwrite\ourwrite
\immediate\openout\ourwrite dum.dum
