bug#4846: 23.1; File Shadow: Shadowing to FTP server does not work

[Martin Apel]

I have tried to set up file shadowing so a local file is shadowed to an FTP 
account.
The file .shadows looks as follows:

(setq shadow-clusters nil)

(setq shadow-literal-groups
  '(("/ftp:mylogin@myftpserver:~/private/test" "/martin@gandalf:~/test")))

(setq shadow-regexp-groups nil)

After modifying the test file locally and invoking 'shadow-copy-files' the 
message buffer contains the following:
Tramp: Opening connection for martin@ftp using scp...
Tramp: Waiting 60s for local shell to come up...
Tramp: Sending command `ssh ftp -l martin  -q -e none && exit || exit'
Tramp: Waiting for prompts from remote shell
File error: Process died
Shadow /ftp:mylogin@myftpserver:~/private/test not updated!
Wrote /home/martin/.shadow_todo

Unfortunately the documentation is rather vague, so I might not have set up 
shadowing correctly.
