Review Comment:
there seems to be quite a bit of formatting code here -- but many of the
cases are not covered by the tests
can you explain what it is trying to do?
Perhaps you are trying to make the expressions better to read, similar to
- https://github.com/apache/datafusion/issues/15107
What I suggest for this PR is:
1. Follow the existing patterns for `tree` mode
2. Ensure any important case is covered by tests
And then we can work on making expression printing nicer as a follow on PR
(and so it applies to all `tree` modes)
