pycomedi_demo_args: comment on what happens with lots of verbose args.

For example, if you call

  cmd.py -vvvvvvv

This will set pycomedi.LOG to DEBUG.

  WARN -> INFO
  INFO -> DEBUG
  no-op
  no-op
  etc.

The new comment makes this clearer, because it took me a minute to
understand the implementation ;).
