For this changes I would expect for \use_dash_ligatures to be referred in the FORMATS since this is a new header that does not exists before. At the same time I would expect for this header to be set every new documents, either to be true or false depending on the file content. Or as you describe depending on the initial starting file format. We want that as much as possible the result of a lyx2lyx file conversion to be equal to the same content read and exported by lyx without any further changes Regards, -- José Abílio
