> The non-multiline CSV read codepath contains references to removal of blank
> lines throughout. This is not necessary as blank lines are removed by the
> parser. Furthermore, it causes confusion, indicating that blank lines are
> removed at this point when instead they are already omitted from the data.
> The multiline code-path does not explicitly remove blank lines leading to
> what looks like disparity in behavior between the two.
> The codepath for {{DataFrameReader.csv(dataset: Dataset[String])}} does need
> to explicitly skip lines, and this should be respected in {{CSVUtils}}.
