statuses and transferred for ResultRows, fix row splitting
    
    Make it so you can specify the 'statuses' and 'transferred'
    parameters for Result objects when getting ResultRows - this
    involves passing the parameters through rather a long chain of
    functions, but I don't see a more elegant way to do it. Also
    fix row splitting to use a regexp to handle cases where there's
    whitespace in the row separator line.
