csvcut: Special case if only -C is provided for CSVs with ragged rows

I expected the second line to be bar,baz since all I asked for was to remove the first column. Similarly, I expected the third line to be empty since there was only one column in the input file which was removed. I can see why in many cases the output above may be desired, but that seems like more of a job for csvclean.
