    gdkcontentserializer: Use newlines for file separators
    
    Use newlines rather than spaces to separate file paths (or uri's)
    when serializing text/plain files.  There isn't a matching
    deserializer, so we can do this in isolation.  Newlines
    seem to make more sense when pasting into a text editor etc.
