[issue2054] add ftp-tls support to ftplib - RFC 4217

[Giampaolo Rodola']

Giampaolo Rodola' <billiejoex at users.sourceforge.net> added the comment:

Ok, so let's leave httplib alone. Let's just add the unwrap() method to
ssl.SSLSocket so that it could be be possible to go ahead with the
current patch.
Modifying it consists in just adding a new prot_c method (I could do that).
As for the cacerts needed to be passed to FTP_TLS constructor you could
do that afterwards.
