Daniel Gustafsson 8d67c61c47 curldown: Fix email address in Copyright
The curldown conversion accidentally replaced daniel@haxx.se with
just daniel.se.  This reverts back to the proper email address in
the curldown docs as well as in a few other stray places where it
was incorrect (while unrelated to curldown).

option.

CURL *curl = curl_easy_init();
if(curl) {

curl_easy_setopt(curl, CURLOPT_USERAGENT, "Dark Secret Ninja/1.0");
curl_easy_perform(curl);
}
}
