I too think it would be nice if these messages were not shown if
Csound did not run. I looked at the code and if you uncommented it it
will respect msgLevel, but that in itself doesn't satisfy whether
Csound has run or not (which is what the comment mentions). I think
it'd be fine to uncomment that msgLevel check, and checking if Csound
ran or not could be addressed separately.
