nginx + php-fpm: commented out custom php.ini settings get into pool config
if you comment out valid php-settings like this, they get parsed and put into the pool config in a wrong way:
Custom php.ini settings: ;upload_max_filesize = 2M
result in /etc/php5/fpm/pool.d/webX.conf: php_admin_value[;upload_max_filesize] = 2M
