	PR c++/31993
	PR c++/32252
	* 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.
