[Duplicity-talk] Entering wrong ssh password with --ssh-askpass

[Marcin Zajączkowski]

Hello,


Entering a wrong ssh password (when using --ssh-askpass switch) causes 
Duplicity to try 5 times to login using that wrong password (of course 
without any chance to login). Retries are good, but for a wrong password 
it doesn't have sense.

Would it possible to detect that error and (with --ssh-askpass) ask for 
a password again?

Duplicity 0.4.11, Fedora 8.

<OUTPUT>
Password for 'my-host':
Running 'sftp  address@hidden' (attempt #1)
Invalid SSH password
Running 'sftp  address@hidden' failed (attempt #1)
