Oops. I spoke too fast. That "sounds like a good idea" of mine was a response to your:

... so the patch still needed some fixups. It had minor dependencies on the previous patches in the series as well, so I tried to fix them up myself.
Could you take a look at it and see if the following is good enough, please?

Subject: [PATCH] Return CURL error message when object transfer fails
From: Nick Hengeveld <nickh@reactrix.com>
Date: 1127757131 -0700
Return CURL error message when object transfer fails
[jc: added similar curl_errorstr errors to places where we
use curl_easy_perform() to run fetch that _must_ succeed.]
