Useful future statement support for the interactive interpreter (Also remove warning about module-level global decl, because we can't distinguish from code passed to exec.) Define PyCompilerFlags type contains a single element, cf_nested_scopes, that is true if a nested scopes future statement has been entered at the interactive prompt. New API functions: PyNode_CompileFlags() PyRun_InteractiveOneFlags() -- same as their non Flags counterparts except that the take an optional PyCompilerFlags pointer compile.c: In jcompile() use PyCompilerFlags argument. If cf_nested_scopes is true, compile code with nested scopes. If it is false, but the code has a valid future nested scopes statement, set it to true. pythonrun.c: Create a new PyCompilerFlags object in PyRun_InteractiveLoop() and thread it through to PyRun_InteractiveOneFlags().
