Override default Console help text - symfony

Question

I want to cleanly override part of the default text output by Symfony\Component\Console when either the help or list command is used. In particular, the gratuitous line wrap of the verbosity option bugs me a lot although I may ultimately want to alter the rest of the help/list text a bit as well.
I.e. this line of output:
--verbose -v|vv|vvv Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug.
Would be nicer if I could change it to something like:
--verbose -v|vv|vvv Set verbosity level.
I could subclass Symfony\Component\Console\Application and override the getDefaultInputDefinition() method.
I perhaps could use a combination of getDefinition() and setDefinition() to fiddle with the InputDefinition object.
But these don't seem to be very maintainable.
Is there some other, better, way to accomplish this?

Try this. I'm not certain it will work but looks like the closest solution.
use Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\InputOption;
public function overrideVerboseInputOption(Application $application)
{
$verboseOption = $application->getDefinition()->getOption('verbose');
$customVerboseOption = new InputOption(
$verboseOption->getName(),
$verboseOption->getShortcut(),
InputOption::VALUE_NONE,
"Set verbosity level"
);
$options =& $application->getDefinition()->getOptions();
unset($options['verbose']);
$application->getDefinition()->addOption($customVerboseOption);
}
