The CSV format is rather underspecified as it is.  csvtool was written
based on what a certain popular spreadsheet can do, plus much folk
wisdom.  Changing the delimiter doesn't particularly help.

Basically you have to be able to parse CSV files like this one from
the csvtool test suite:

----------------------------------------------------------------------
"This is a test
with commas,,,,,

and carriage returns
and "0",a second field,a third field
a fourth field on a new line
----------------------------------------------------------------------

(That CSV file has two rows and three columns)
