the title says it all. it has to do with this edit in which all i needed to do was add a couple of backslashes. but i have run into that problem before. so i end up changing more than i intended, just to get the system to tentatively accept the edit.
also, with this very question, i am getting "This question body does not meet our quality standards...."
