It depends on what you mean by "proceed". I understand that you want
to see the corresponding DEFVAR_* line, is that right?

It's not a Lisp variable. It's a C variable that has a Lisp binding.

Your wish has been granted in commit 8d69f38.

It will now offer both. (I don't think I agree with that "never"
part, because it is important, and exactly what the user wants, in
some use cases, although evidently not in yours.)
