The 'LOT more ftp traffic' is very good reason for not doing it.  It would
mean lots of round trips and waiting.

It works for me with 'nlist -lg' which my client sent as 'NLST -lg'.
But I didn't see any string in that server's responses that could be
used to trigger attempting this in lynx (except for the human-readable
greeting message, I doubt we want to parse that).

'NLST' without arguments also works as expected.  But the same applies,
the server claims to be Unix so Lynx treats it as such.

Squid 2.1.2 has a problem with this server, too.
