## Summary
And more custom logic around comments in bodies... uff.
Let's say we have the following code
```python
if x == y:
pass # trailing comment of pass
else: # trailing comment of `else`
print("I have no comments")
```
Right now, the formatter attaches the `# trailing comment of `else` as a trailing comment of `pass` because it doesn't "see" that there's an `else` keyword in between (because the else body is just a Vec and not a node).
This PR adds custom logic that attaches the trailing comments after the `else` as dangling comments to the `if` statement. The if statement must then split the dangling comments by `comments.text_position()`:
* All comments up to the first end-of-line comment are leading comments of the `else` keyword.
* All end-of-line comments coming after are `trailing` comments for the `else` keyword.
## Test Plan
I added new unit tests.
