This seems to work:

>> %Q{,,,,"xyz",,,,}.split(",", -1).map { |f| f.empty? ? nil : f }
=> [nil, nil, nil, nil, "\"xyz\"", nil, nil, nil, nil]

Again, do not set :quote_char and :col_sep to the same value. That's
impossible to parse. Also :force_quotes is only used when writing
CSV, not reading it.
