Subject: [PATCH] This commit fixes a bug in biblio encoding. things were mixed
 up when reporting item(s) into the biblio, to UPDATE biblioitems.marcxml,
 after a biblio modif (in MARC editor).

So, deal carefully with this commit pls, and check it for your setups, because the patch works for me, but I'm not sure to understand well why :\
