it is not what i meant -----"the editMenu--->wrap".
what i mean is, wrap a line visually(it well be still a line),not physically by adding "\r\n".
their could be two purpose that make you feel missing the piont which i think is important:
1.the view-wrap has the purpose of visual convenient.
2.the indent make the doc have structure between lines(paragraphs), what does those structure mean depend on others(app,person,definition)how to interpret it.
