A wrong message is used when adding *or* removing aliases:
Adding: http://www.wikidata.org/w/index.php?title=Q183&diff=prev&oldid=2032&uselang=en
"Added and removed [de] aliases: BRD, BR Deutschland"
Removing: http://www.wikidata.org/w/index.php?title=Q183&diff=next&oldid=2032&uselang=en
"Added and removed [de] aliases: Bundesrepublik Deutschland, BRD, BR Deutschland"
Adding and removing in 1 actions are ok: http://www.wikidata.org/w/index.php?title=Q183&diff=2220&oldid=2217
The existing messages 'wikibase-item-summary-wbsetaliases-add' and 'wikibase-item-summary-wbsetaliases-remove' seems unused.
