The new test first checks whether the user exited the editor
without editing the file, then whether what the user was
presented in the editor was any useful to her, which we define
as the following:
 * It begins with a single blank line, where the invoked editor
   would typically place the editing curser at so that the user
   can immediately start typing;

 * It has some instruction but that comes after that initial
   blank line, all lines prefixed with "#".

 * And it has nothing else, as the expected behaviour is "Hey
   you did not leave any message".
