list.Reverse();
list = list.SkipWhile(l => l == 0).ToList();

I have seen several (suggested) reviews lately, where someone edits the code in the original poster's question. Should such edits be allowed?
The edits in question are mostly minor. Some add spaces to the code to increase readability, others fix syntax errors in the posted code.
Some questions link to the code they want reviewed, which is against site policy. Should one edit the code into the question in these cases?
