fixup: clarified :EX behaviour on modified unnamed files

 * when the unnamed file was modified, :EW would just succeed discarding
   all changes to the unnamed file.
 * Instead now, :EX behaves like the EW$ command on each modified buffer
   including the unnamed file.
 * In other words, :EX will fail if there is a modified unnamed file
 * still refers to #4
