ftp_rawlist bogus with aliases?

The ftp_rawlist function seems to have problems handling symlinks (tested with wu-ftpd)

if I ftp_chdir and then ftp_rawlist($fd,".") then the server gives a complete (and recursive) listing of the directory and its childrens
if I ftp_rawlist($fd,$dir) and $dir is a symlink, then the listing shows... the symbolic link itself

Therefore, is this function useless since you have symbolic links to manage directories?

ftp_rawlist($fd,"") problem : This is a bug, which I reported at:

The bug is due to the wrong 'LIST ' command

The only temporary trick to list the current directory in raw mode is to do a
ftp_rawlist($fp,"-l") that generate a LIST -l
