The motivation for this question is this post: http://tex.stackexchange.com/posts/94206/revisions
In one of recent edits, the editor decided to change the code formatting in a piece of
lisp code. Since the code was not badly formatted before, I decided to rollback it, because I felt that code formatting style is a matter of personal preferences, there are many valid ways to do it and editor should not change it.
After some short discussion in the chat and coming to no conlusion, it was decided that more discussion is needed.
So the question is: Is it acceptable to edit the code formatting in a post by another user when the formatting is not bad and has no influence on the function of the code?
