The attached patch comments out the line that calls the macro that
adds this dummy token. It works with the test file attached.

All I can think of at the moment is not to add the dummy token at the
end of the argument, and not use the backslash as the last character
of the argument of the macro. It will work sometimes, depending on
which token a final backslash absorbs, but there are likely cases when
this could cause a problem as well.

I'd like to make the @macroargdummy token completely disappear at some
point, but maybe it isn't possible.
