Here's the update:
- It's much better, almost right.
- The user prompt says "user blabla: monnier", rather than "user blabla
  (default monnier): ".  I.e. the `initial-content' should be empty, and
  the user name should be passed as `default' instead.
- The "save password" prompt shows up not only after I entered the
  password, but also when re-connecting (and using the password kept in
  memory).
