verbose output can be silly long if repeated multiple times.
Perhaps the verbose content should only be printed once when
first emitted with a flag set for that type.

Something like:

	if ($verbose && exists($verbose_messages{$type}) &&
	    !$verbose_emitted{$type}) {
		$output .= ...
		$verbose_emitted{$type} = 1;
	}
