    unlockDialog: set password char on verif. failure
    
    Commit c3cab28 removed bits setting the password char that was used to
    allow typing the password after a failure but before the first question
    for the new attempt came.
    
    Without that code, in complex PAM setups you can end up with a visible
    password.
