I have just uploaded this patch with the header (sorry for cutting it off)--it
should apply smoothly now. 

There are apparently some problems with variable scoping / dereferencing in the
SEARCH_RESULT.available_items_loop construct.  

Previous (i.e. 3.2) the behaviour was: if there are no items attached at all
(just the biblio record) or no item is available (e.g. all items checked out)
then "No items available:" message is displayed bellow the title etc. on the
collective search results list.  As I look at the new template, now it should
be the same.  

BUT is not.  Even if there no items in available_items_loop, the result of the
test [% IF ( SEARCH_RESULT.available_items_loop ) %] is positive (I do not know
why) and you get "Copies available:" message.

To see this try with records with no items attached both in Koha 3.2 and in
3.4.

So, what the patch does is: it checks explicitly if the first element of the
array available_items_loop exist (instead of checking if available_items_loop
is not empty).  It is less elegant, but it means the same and it does work as
expected.
