From 468d94ded336883fc7dfcb2112428e6f164178e4 Mon Sep 17 00:00:00 2001
From: Aleisha Amohia <aleishaamohia@hotmail.com>

Subject: [PATCH] Bug 16522: (follow-up) MARC display templates and
 get_marc_host fixes

Also:
- Show related parts 773$g
- Normalise using 'Host item entry' as title
- Remove 'foreach' because non-xslt views only return first
- If no $w, use $atg, and related tests in
t/db_dependent/Koha/Biblio/host_record.t
