Describe the solution you'd like It would be great if the user could set a specific newline character in the configuration file, which would be used when calling mh_style --fix. The options could be lf, crlf and platform_dependent, which would set newline= to "\n", "\r\n" or None respectively in the open function here: https://github.com/florianschanda/miss_hit/blob/f01fbf9cd43c52fdb8fe6dce162c9772637ec199/miss_hit_core/work_package.py#L114 This would be of great help to get reproducible results for teams developing in multiple different platforms.
