Hi guys,

found the following bug:

When I specify both the RESUME_FROM and/or the RANGE option and
the connection broke down before the download will abort with an
error.

In the following example I used both setting them to the same
start byte because it is easier to reproduce but I get the same
behaviour when the connection times out and I use just the RESUME_FROM
option instead of the RANGE. Of course the error message at the bottom
is wrong and the server does support ranges as the reply shows.

startoffset = image_offset;
endoffset = image_offset + rootfs_size - 1;
snprintf (range, sizeof (range), "%d-%d", startoffset, endoffset);
curl_easy_setopt (curl, CURLOPT_RESUME_FROM, startoffset);
curl_easy_setopt (curl, CURLOPT_RANGE, range);
curl_easy_setopt (curl, CURLOPT_WRITEFUNCTION, RootfsReader);
res = curl_easy_perform (curl);
