[Bug-wget] LIST command supported by WGET

[李明]

Hi, I use wget-1.11.4 to download the file successfully from my FTP server 
which wrote by myself. When I updated wget to  verion 1.16 , I found that 
download file failed. The reason is my FTP server only support 'LIST' command. 
In this case wget-1.16 run in the case  UST_TYPE_L8，using 'LIST -a' as a 
standard command.

In RFC0959(FTP), the ”LIST -a“ is not declared clearly a standard command. So I 
personally think that in this case it would be without compatibility. Is it 
more reasonable to try "LIST -a" then "LIST"?
Thank you very much.
