    sftp: Ignore leading whitespace during login
    
    If logging in without an agent, g_str_has_prefix (buffer, "Enter
    passphrase for key") fails the second time around (e.g. if the first
    entry was incorrect) because the buffer contains a leading newline: "
    Enter passphrase for key '/home/user/.ssh/id_rsa': "
    This makes the login process timeout.
    
    To fix this, trim leading whitespace.
