Bug 25871 introduced a new option and bug 24352 corrections for OpacItemLocation but none of them seems to be apply with Unimarc. Could be great if it could apply to all Marc formats because it's quite confusing to have syspref descibed as generic (non MARC specific) that finally doesn't work.
Amazingly... I don't see any references in Koha's code indicating use of this system preference. Adding Marcel as I know he has done some work on results lists more recently.

And it only appears in MARC21 XSLT files.
