Equality isn't well defined: sometimes we want content equality, other times we want reference equality. It's easy to screw up.

Append trailing text as atoms if we encounter ERROR nodes

``` test: foo: 'a' ``` ``` test: foo: 'b' fail: true ``` Spotted in #266. The YAML parse tree does not include `fail: true`.

Slow diffing of fs/io_uring.c in Linux

Compare v5.16..v5.17 -- shows a bunch of syntax errors too.

See src/parser.c in 06dfec714e2424be9d19aacb739771746f5aec2b (introduced in vendored dir in a7e298dfa19fb75b55958233f6d0d759da646ed9). Looks like the rust parser.

Now that we're splitting trees into regions before diffing, this could be parallel if change state wasn't in the tree.

See e.g. 3ba0a6808a9da313de67ec8a23456fcb2ed0fbb5 

Prefer duplicate tokens on the same line

See e.g. 14b52e6ac04fcc77c3a8123cbbf3dc78451adff3 in hhvm, in `naming.ml`.

This would be interesting for e.g. Rust assertion failures.
