So something with the same semantics as this:

(defun find-nearest-heading-named (l)
  (unless (find-heading-in-current-subtree l)
    (up-one-level)
    (find-nearest-heading-named l)))

i.e find the target with its parent headings list sharing the longest
prefix with current point's.

* A
** B
* C
** B
** D
*** B
*** E

A link to B inside E would go to C/D/B because (C D B) shares longer
prefix with (C D E) than (C B) and (A B) does.
