From 26fa2de9146e1cdc0e086f85ff63264920c7ceca Mon Sep 17 00:00:00 2001

Subject: [PATCH] Bug 4506: Add links to other editions, some minor corrections

A new label 'Other editions:' is added with links to other editions.
The link starts a search for control number from 775$w in index control number.

A check for existence of $w/001 is added to always provide a fallback to a search for the link text.

Take care of repeated 773 fields.
