- Move the tests to tall. The old short style formatter doesn't support new syntax and doesn't need to be tested. - Add support for passing experiment flags with tests. The old way of doing this was to just hardcode experiments inside the formatter when a new feature was supported. That made sense when the formatter didn't know about language version, but now that it does, it should probably require experiment flags explicitly and tests for new features should enable them. - Move the code to handle "? into visitMapLiteralEntry(). The AST node does have tokens for "?" and that way there's less special-case code getting threaded through PieceFactory. - Add some tests for comments appearing around "?". (Comments tend to be a tricky corner of the formatter, so we test them heavily.)
