Another incremental change to diagnostic formatting. I simply recurse over all the tokens in the subtree of a parse node and construct a `DiagnosticLocation` that covers all of the tokens. I believe it's nicer for the user to be directed at the entire chunk of source where the error is occurring rather then just pointing at the bracketing/terminator tokens, but let me know if you all agree.
