There used to be a mechanism somewhat against this, namely when many users made many edits, the post became Community Wiki and no more points were gained.
This state of affairs had its own set of problems to it and thus it was abandoned. It is not very clear how the problem could be solved in an automated way.
The general line in all this is that the points are a vague measure. A couple points here or there are irrelevant.
If you personally have a problem with it, depending which one it is, just do not do the edit or do not upvote the edited post.
In extreme cases you could consider flagging the post for moderator attention for it to be made CW. (I am not sure how I would react as moderator, but since CW-ing questions is still sometimes done on this site it seems like a possibly plausible course of action.)
