Use pretty-simple to format native output. Previously we used our own homespun formatting. But this produces over-long lines that aren't ideal for diffs in tests. Easier to use something off-the-shelf and standard. Closes #7580. Performance is slower by about a factor of 10, but this isn't really a problem because native isn't suitable as a serialization format. (For serialization you should use json, because the reader is so much faster than native.) 2021-09-19 12:09:51 -07:00			`[ Para`
