+7.9 Passive transfer tries only one IP address
+
+ When doing FTP operations through a proxy at localhost, the reported spotted
+ that curl only tried to connect once to the proxy, while it had mulitiple
+ addresses and a failed connect on one address should make it try the next.
+
+ After switching to passive mode (EPSV), curl should try all IP addresses for
+ "localhost". Currently it tries ::1, but it should also try 127.0.0.1.
