Avoid treating an expanded comma as an argument separator.

That is, a function-like invocation foo(x) is valid as a
single-argument invocation even if 'x' is a macro that expands into a
value with a comma. Add a new COMMA_FINAL token type to handle this,
and add a test for this case, (which passes).
