Oki, I understand. To me, this info on modeline is superflous. When I am
in dired buffer, I have immidiate visual feedback by just lookig at the
content. I see if the content is sorted alhabetically or by some other
means, for example size (which is not reflected at all on modeline.)

Also I like the possibility of user having option to customize
this like everything else in Emacs. I will try to code another idea
later in the evening as another suggestion.
