It only happens for ftp in passive mode AFAICS. The reason may be to
tell you when you've been redirected off the original host (in response to
the PASV command). But I'm not really sure why, Daniel?

So don't use "--verbose" (or -v) in curl. Alternatively temporary toggle
CURLOPT_VERBOSE to off state in your program using libcurl.
