We don't call the generic print on the BinaryExpression itself, so we need to manually print those comments. It's going to be useful for my work on the MemberExpression :)
It's actually not needed to use conditionalGroup as we can use ifBreak for it. I was able to do it just for cleanup and found out that it also fixed two of the bugs we have with comments. That's great :p

The original intent of it was for `if then else` and `try catch` as they aren't likely to be empty, but it accidentally caught function bodys, which have many valid reasons to be empty. Let's special case those out.
