>> 1. emacs -Q

>> 6. Move point to column 0 of the first "message" sexp.
>>    => Now "LIST" is highlighted in the echo area.
>> 7. Move point to column 0 of the second "message" sexp.
>>    => Now "[RESULT]" is highlighted in the echo area.
>> 8. Move point to column 0 of the third "message" sexp.
>>    => Now "BODY" is highlighted in the echo area.
