It's hard to track 2-space indent levels across large vertical gaps, and it can be hard to suppress the instinct to read the dump as if it were preorder. This change introduces a new dump mode that addresses both problems by using box-drawing characters to explicitly represent the parent-child edges of the tree. This new mode is the default, but the old behavior remains available with `--parse-dump-format=yaml-postorder`.
