When I type in \"A the minibuffer displays the sequence \"A (no digit!)
and the buffer displays an underlined Ä. In this state (S):

1. Pressing TAB displays the message

Possible completion and corresponding characters are:
 \"A:(1/1) 1.Ӓ 2.Ǟ 3.Ä

2. Pressing the digit 1 results in the buffer containing
Ä1, this happens in state (S) and also if hit TAB to pop-up the message
displayed in 1. Similar behaviour is observed for other digits and other
key sequences (like \"u).
