This is due to this code:

(defun help-make-xrefs (&optional buffer)
[...]
      (goto-char (point-min))
      ;; Skip the header-type info, though it might be useful to parse
      ;; it at some stage (e.g. "function in `library'").
      (forward-paragraph)

Anybody know what the rationale behind this is?  I in complex values,
there may be false positives, but...  I tried just removing that bit and
looking at a couple of variables, and it fixes the problem described
here, and I didn't see any regressions.

Complex variable values aren't displayed here (but at the end of the
buffer), so that shouldn't be a problem.

Any opinions?
