[bug #60106] wget mistakenly interprets Content-Range as bytes, even with Range-Unit: items, and truncates content

[Tim Ruehsen]

Update of bug #60106 (project wget):

                  Status:                 Invalid => Confirmed              
             Open/Closed:                  Closed => Open

Follow-up Comment #5:

Thanks for reporting this.

Just skimmed the specs ... well, the server is special in several ways and
seems to interpret standards "in his own way".
I'd even say it's simply buggy and should be fixed.
(E.g. the "Content-Range:" format is simply wrong regarding
https://tools.ietf.org/html/rfc7233#section-4.2).

Anyways, wget should simply ignore the broken and the undefined HTTP headers
and save the response body. The Content-Length header gives all the
information needed (4027 bytes in the example below). I am sure that curl does
exactly that.

The unregistered (private) Range-Unit header is already ignored by wget, so it
has nothing to do with this issue. The title of this issue was possibly a bit
misleading, so I'll amend it.

I'll reopen the bug, as IMO we should fix the behavior of wget here.
