        * pt.c (find_parameter_packs_r): Fix typo in comment.
        (convert_template_argument): Look at the pattern of a pack
        expansion to determine what kind of entity we're converting.
        (coerce_template_parameter_pack): When we have coerced a non-type
        template parameter pack, substitute into the type of that pack.
        (tsubst_pack_expansion): When our substitution of a parameter pack
        is a "trivial" substitution of itself, just substitute into the
        pack expansion rather than actually expanding.
