I'd be inclined to define Excel 2000 as broken, honestly, if it's
writing unescaped newlines as data. To support this would mean throwing
away most of our ability to detect incorrectly formatted CSV files.
A simple error like a missing close quote would look to the machine like
the rest of the file is a single long data line where all the newlines
are embedded in data fields. How likely is it that you'll get a useful
error message out of that? Most likely the error message would point to
the end of the file, or at least someplace well removed from the actual
mistake.
I would vote in favor of removing the current code that attempts to
support unquoted newlines, and waiting to see if there are complaints.
