It turns out, that dev.13 now hangs in some circumstances
(it is easier to detect when lynx compiled with find_leaks -
just visit Lynx_user_guide.html and press reload a couple of times,
then try to exit).

Apparently, HTList_unlinkObject doing an infinite loop -
some node was relinked several times so the previous list chain
was corrupted.  (The real thing is the reloading with ^R
it deletes HText but *not* HTParentAnchor structure so all subanchores
will have several duplicates.)

Here a quick fix:


* HTList_linkObject now safe
* HTAnchor_link now link only foreign sources.
