In GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, X toolkit)
 of 2013-04-02 on a1i15
System Description:	Gentoo Base System release 2.2

To reproduce:

   $ emacs -Q -nw
   i
   C-x 8 RET 0 3 2 f RET

(i.e., the buffer now contains an "i" followed by a "combining inverted
breve below")

   C-b 
   C-u C-x =

Amongst other things, this command outputs:

   Composed with the following character(s) "̯" by these characters:
    i (#x105)
    ̯ (#x815)

Now 105 is the decimal value of the character code for i. It should
output #x69 instead (or, alternatively, omit the #x).

Here is a patch, AFAICS it should also apply to the trunk:
