The whitespace should come from the argument name in the macro expansion, rather than from the token passed to the macro (same as it does when not pasting). Added a new test case for the change in behavior to stringize_space.c. FileCheck'ized macro_paste_commaext.c, tweaked the test case, and added a comment; no behavioral change to this test.
