   A tricky, pathological corner case we used to get wrong.  Expansion

   should go as follows.  The asterisk indicates the token has "blue

   paint" can no longer be macro expanded.  We used to lose that

   information when parsing arguments and dropping to the lexer to get

   the ')'.

   foo )

   bar foo* )

   func (foo* )

   foo*

   If we try and expand the final foo, we get an "unterminated

   argument list invoking macro <func>" error.  If we do the right

   thing and leave it as is, no diagnostics are emitted.  */
