Unimplemented option '--ignore-length'

From docs:

--ignore-length [Not implemented yet]

Unfortunately, some HTTP servers (CGI programs, to be more precise) send out bogus "Content-Length" headers, which makes Wget2 go wild, as it thinks not all the document was retrieved. You can spot this syndrome if Wget retries getting the same document again and again, each time claiming that the (otherwise normal) connection has closed on the very same byte.

With this option, Wget2 will ignore the "Content-Length" header as if it never existed.
