Re: RFC: Change to the way sh -x works?
This looks very useful to me. I guess SUS doesn't specify this?

I can't unambigiously parse that. On second reading, treating the comma at
the end of the first line more as a semicolon or full stop, I stumble over
what "nothing changes" means: The shell treats this as a no-op or the shell
behaves as without your change? From further reading, I guess it's a no-op.
> And yes, if tracing is off, "set -x 2>/tmp/trace-file" works as expected
This is brilliant!
