Note: formatc.lua was unable to swallow some newer additions to ExprASTNodeType (specifically `kExprNodeOr = '|'` and probably something else), so all `= …` were dropped: in any case they only were there in order to not bother updating viml_pexpr_debug_print_ast_node and since it is now known all nodes which will be present it is not much of an issue.
