Indeed. Your comment made me realize that my suggestion was the exact
opposite of the earlier d5ccbe4df (remote-curl: consistently report repo
url for http errors, 2013-04-05). :)

Given that we don't see a lot of questions on the list about this,
either it doesn't come up much, or they are capable of finding
GIT_TRACE_CURL or GIT_CURL_VERBOSE on their own. So I think we can leave
the message as-is.
