The csv module handles multi-line fields and the authors went to great pains
to try and read/write Excel-compatible files.  I believe in Excel that an
embedded newline is just a newline, not CRLF.  If the files are throwing off
vim or Emacs that's not all that surprising.  How they interpret files with
mixes of CRLF and LF is anyone's guess.
