I've recently learned how to properly line break with two spaces at the end of a line.
So I tried editing a post that had lists and stuff without proper linebreaks. Two spaces at the end of each line solved it... until the edit was rejected because it had less than 6 non-space characters. So I put in a few
<br/> tags, and it happily accepted those.
So, should my edit have been accepted? Is the system's discrimination between them intentional or not?
