So? This doesn't look amazingly unlike the current JSON output,
and to the extent that we have to add more quoting to it, it's
going to look even more like the JSON output.

Given the lack of any field separators other than newlines, I'm also
finding myself extremely doubtful about the claim that it survives
line-wrapping mutilations well. For instance this bit:

- Node Type: Seq Scan
Parent Relationship: Outer

doesn't appear to have anything but whitespace to distinguish it from

- Node Type: Seq Scan Parent
Relationship: Outer
