inappropriate use of watchdog - translation and xss vector

$message = 'LESS ERROR: '. $e->getMessage() .', '. $input_file;
watchdog('LESS', $message, array(), WATCHDOG_ERROR);

That is both not translatable and could be an XSS vector.

It would be better as something like:

$message = 'LESS error: @message, @input_file';
watchdog('LESS', $message, array('@message' => $e->getMessage(), '@input_file' => $input_file), WATCHDOG_ERROR);

Because it requires the ability to write files to the server the XSS is considered a secondary issue and can be fixed publicly.
