Hello,

a forwarded bug report from a Debian user https://bugs.debian.org/843620

--8<--
It would be nice if the behavior of --continue would also handle
corner cases, such as the following:

$ wget --content-disposition --continue
http://www.mckesson.com/documents/providers/mckesson-radiology-12-dicom-conformance-statement/
--2016-11-08 12:48:07--

connected.

On the other hand this one works OK:

$ wget --content-disposition --continue

For some reason HEAD would not get the Content-Disposition tag, but
looking at curl output I can see it:
