Glancing at ftplib, the difference is that my suggestion will send REST,
PORT/PASV, RETR (in that order), but ftplib does PORT/PASV, REST, RETR.  A
quick glance at http://cr.yp.to/ftp/retr.html doesn't suggest that this
should matter, but this is FTP after all...  (and it wouldn't surprise me if
different servers behave differently here, too)

Looks like FTPClient will need to be changed after all :/
