[plug] Allow SSH but deny SFTP?

Why do you want to stop sftp? Do you want to stop "ssh cat\ remotefile >
local file" as well?

If you just to discourage users  from accidentally violating some anti sftp
policy, something like `chmod 750 /usr/bin/sftp` might work

This clearly wouldn't prevent the user from using other ways of using their
ssh account as a filesystem. If you want to discourage that you could try
limiting bandwidth to 64Kbps.
