Problem/Motivation Some configuration values are multiline (mails, system.maintenance & etc) but their export contains "\r\n" to split lines. That makes configuration merging hard for such strings and mostly impossible to use configuration translations management for big config objects (for example webforms [#2836206]) Proposed resolution Beautify export and make diff/merge tools less painful http://symfony.com/doc/3.1/components/yaml.html#dumping-multi-line-literal-blocks
