Based on an error report by Philippe Vaucher, we no longer count a retried 

connection setup as a follow-redirect. It turns out 1) this fails when a FTP

wrong. This fix was not verified since the reporter vanished, but I believe
this is the right fix nonetheless.

This release includes the following bugfixes:
o re-creating a dead connection is no longer counted internally as a followed
redirect and thus prevents a weird error that would occur if a FTP
connection died on an attempted re-use
o Try PASV after failing to connect to the port the EPSV response contained
o -P [IP] with ipv6-enabled curl
o -P [hostname] with ipv6-disabled curl
