Curious.  Guess it wasn't the case at some point.  I checked Insight
too, and its interpreter creates a plain cli_out, not a custom
ui_out, so we're good there too.  I'd push the patch as you had it,
and the clean the method to return void, which will result in some
cascading clean ups at the callers.

Thanks,
