[Bug-wget] problem with --continue and already completed ftp downloads

[Eike Kohnert]

Hi all,

i use wget to download a complete directory from a ftp server and want 
to download new files every day.

I use a command like

wget --continue ftp://someserver/somedirectory/*.ZIP

It seems like wget tries to resume files, even if they are already 
finished. I sniffed the generated network traffic and found something 
like this:

SIZE XXXX.ZIP
213 872953
PASV
227 Entering Passive Mode (....).
REST 872953
504 Reply marker must be 0.
RETR XXXX.ZIP

I think wget should not do the REST command because the retrieved size 
equals the size of the already downloaded file. So the resuming download 
would download only the remaining 0 bytes which does not make much 
sense. On servers which do not support resume this will cause the whole 
file being downloaded again.

I used wget version 1.12

Best regards
Eike
