The problem with directory listing in the ftp protocol is known:
rfc 959:
Since the information on a file may vary widely from system
to system, this information may be hard to use automatically
in a program, but may be quite useful to a human user.
New commands have been proposed, see the abbstract of
http://www.ietf.org/internet-drafts/draft-ietf-ftpext-mlst-16.txt
In order to overcome the problems caused by the undefined format of the
current FTP LIST command output, a new command is needed to transfer
standardized listing information from Server-FTP to User- FTP. Commands to
enable this are defined in this document.
I think that there is little to do for the existing ftp protocol. Also because
NLIST is not always implemented, if LIST is implemented. And this happens also
if the http://www.wu-ftpd.org/rfc/rfc1123.html says (1989) that NLIST MUST be
implemented.
