Remove nil values from rows

[pezholio]

It seems that the CSV parser returns nil if there is a comma and then a blank. I don't think we want this, so I've stripped nil values from the generated array. Now https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/246500/New_Year_Honours_2013_full_list.csv/preview returns loads of errors, as expected

Coverage remained the same when pulling cf65d28 on bugfix-remove-nil-from-rows into ba034f4 on master.

Will it return the same number of nils even if there are commas missing? Because I'd expect an empty field to come back nil, so this seems... dangerous.

Are you sure that's the right behaviour? It's OK for there to be empty cells within a row. Does this make the distinction between missing values within cells and missing cells, ie between

a,b,c
x

which should give errors and:

a,b,c
x,,

which shouldn't?

[Floppy]

Yeah, that ^

[pezholio]

Yeah, that's why I wasn't sure. I wasn't getting any errors on

a,b,
a,b,c

Which actually should be right. So ignore me.
