Summary: urllib violates rfc 959

Initial Comment:
[forwarded from http://bugs.debian.org/324023]

python's urllib does the following things "on the line"
when retrieving
a file by ftp:
send(3, "PASV\r\n", 6, 0)               = 6
send(3, "NLST ftp-master.debian.org\r\n", 28, 0) = 28

But RFC 959 states:
  This command [NLST] causes a directory listing to be
sent from server
  to user site.  The pathname should specify a
directory or other
  system-specific file group descriptor

So, according to the robustness principle, it is wrong
that python
aborts file transfer if the server refuses to support
NLST on files.

Bug 1357260 reports the same issue for both urllib and urllib2.

"The pathname should specify a directory or other
system-specific file group descriptor."

If the system (ftp server) does not support a particular
'file name' as a 'file group descriptor', it seems to me
that the system (ftp server) is braindead.
