As a follow up on this: all 4 patches have landed in libreoffice 
upstream, but since openSUSE uses its own clucene-core package, it still 
needed some more work:
https://build.opensuse.org/request/show/1188998
https://build.opensuse.org/request/show/1191150

So after 9 months, the story finally reaches its conclusion...

Ciao
