I haven't looked at the code, but it occurs to me that the issue may
be to do with lookahead.  If you're in a quoted string, then "" means
a quote character in the string, but ", or "\n or "<EOF> mean end of
cell.  You can't tell which is which until you read the final
character; specifically, you can't tell if the string has ended until
you read the newline or EOF at the end of the line.

Does that help?
