[Bug-wget] Bug "-c" and "HTTP 405" - HEAD method not allowed

[Bykov Aleksey]

Greetings.

Found possible bug.
If "-c" option is choosen but servers does not allow "HEAD" method, then  
Wget don't download anything.
Sorry, havent any ideas how to solve this.
Variants
1. Ignore 405 error and allow to download with "Range" - possible error  
with HTTP 416
2. Ignore 405 error and re-download whole file?
3. If 405 error then first try to download with "Range" headers, and if  
recieve 416 then try to download without "Range"
May be exist variant to ask server what methods it can accept (and is  
whole server allow downloads resuming) before any actions?
