Here (on Windows), I initially see two, but one disappears after I C-u 
C-x = on it.

In addition to the above, I see all three composed characters if I move 
point through them a character at a time. This shows that the position 
of the following nil is off by one also (but corrects as I move 
through). C-l  results in one composed character being shown with the 
position of the following nil being off by two.

bug#2190: marked as done (23.0.90; Repeated composed characters are displayed wrong.)
