-1. cd /tmp; touch bäh bÄh bla
0. emacs -Q
1. M-x customize-option RET read-buffer-completion-ignore-case RET.
   Toggle to "on", set for the current session.
   M-x customize-option RET read-file-name-completion-ignore-case RET.
   Toggle to "on", set for the current session.
2. C-x C-f b TAB => *Completions* buffer contains, as expected: bla bÄh bäh.         
3. Visit files `bla', `bäh' and `bÄh', switch to buffer *scratch* and
   repeat step 2, replacing `C-x C-f' with `C-x b' => same results.
4. C-x C-f bä TAB => Emacs completes the input to "bäh".               
5. TAB => Emacs incorrectly reports: "[Sole completion]".                 
6. C-x C-f bÄ TAB => Emacs completes the input to "bÄh".
7. TAB => Emacs incorrectly reports: "[Sole completion]".                 
8. Switch to buffer *scratch* and repeat step 4-7, replacing `C-x C-f'
   with `C-x b' => same results.
