I think you want to add one to wanted if decl is a primary template.
OK but I am a little bit dense here: why is that necessary?
By 'primary' I mean something that is itself a template, not just a
member of a class template. Previously variables couldn't be primary
templates, but I believe your proposal is to change that; in that case,
we should expect to see a template header for such a template, in
addition to any headers for enclosing classes.
