Laravel logging: extra square brackets at end of log lines?

Question

I'm newish to Laravel, and I've noticed when I use its Monolog-based logging, e.g. Log::info('blah blah'), the lines it writes to my logfile are suffixed with two empty sets of square brackets. What are they for, and how can I turn them off? They're not helpful in the slightest. I've tried digging into the source code and Googling a bit, but I'm not seeing any explanation.

Example:

[2013-11-12 09:13:16] log.INFO: Hello world [] []

[2013-11-12 09:13:31] log.INFO: My silly log message [] []

Thanks!

Here's a solution which combines curtisdf's answer with this answer by Seldaek, and doesn't require subclassing Monolog's LineFormatter.

Assuming your app/start/global.php file contains:

Log::useFiles(storage_path() . '/logs/laravel.log');

Replace that with:

use Monolog\Handler\StreamHandler;
use Monolog\Logger as MonologLogger;
use Monolog\Formatter\LineFormatter;

// Use custom LineFormatter, with ignoreEmptyContextAndExtra enabled
Log::getMonolog()->pushHandler(
    (new StreamHandler(
        storage_path() . '/logs/laravel.log',
        MonologLogger::DEBUG
    ))->setFormatter(new LineFormatter(null, null, true, true))
);
