Permission check fails to ignore a file directory that is only one level deep

My file system path is "files".

The function security_review_check_file_perms() fails because this code:

$file_path = substr($file_path, strrpos($file_path, '/') + 1);

creates an ignore pattern of "iles" due to the lack of a slash in my path.

Something like this would work:

$file_path = substr($file_path, (strpos($file_path, '/') ? strrpos($file_path, '/') + 1 : 0) );
