Hello developers,
this is my first time contributing to emacs,
i made support for displaying errors in margin for flymake like flycheck
does,
This allows indicating errors in both text and graphical mode.

I've sent my copyright assignment request.

Since this is my first time contributing i would like to hear your
suggestions and thoughts

Thanks.
