As you all know, there are two ways to format blocks of code, four leading spaces in every line vs. three backticks around the code. Many new users know about the first method, but not the second. When I edit a posting due to a spelling error or some other issue (which I frequently do), I often surround a block of code with ``` as well.
As @moewe pointed out to me, this can leave four leading spaces in each line of code (unless there was no code formatting in the first place at all). Are we supposed to remove those spaces? Is there a policy? Does it matter?
