It's not really clear, but ending up with NULL values in parameters
seems a bad thing.  However, I dare see we can fix things up as the occur.

It's not very helpful.

    The shell shall read commands but does not execute them; this can be
    used to check for shell script syntax errors. An interactive shell
    may ignore this option.

But I think there is an argument for setting environment variables in
full.
