Bug: AUTH TLS capability not detected after FEAT

Hi,

Problem: lftp 3.0.2 uses AUTH SSL instead of AUTH TLS, although the ftp
server reports AUTH TLS support (and also, AUTH TLS is working fine with
lftp 2.6.X, on the same server.

Log:

<--- 220 Some Private Server (glftpd 1.32_Linux+TLS) ready.
---> FEAT
<--- 211- Extensions supported
<---  AUTH TLS
<---  AUTH SSL
<---  PBSZ
<---  PROT
<---  CPSV
<---  MDTM
<---  SIZE
<---  SYST
<---  RAIDEN_SUX
<--- 211 END
**** AUTH TLS is not supported, using AUTH SSL instead
---> AUTH SSL
<--- 234 AUTH SSL successful

Things work fine then, using SSL.

One more note: It would be great if lftp could support CPSV (encrypted
FXP). It's really no big deal to support it: lftp should simply send
"CPSV" instead of "PASV", when using FXP while ssl-protect-data is true.
Right now, FXP doesn't work at all when ssl-protect data is set.

bye,
Till
