MediaWiki message (http://www.wikidata.org/wiki/MediaWiki:Wikibase-error-sitelink-already-used) has following code: "Site link [[$1:$2]] already used by item [[$3]]" which produces following message: "Site link [[enwiki:Pierre-François Hugues d'Hancarville]] already used by item [[Q2920822]]". And it should produce following message: "Site link [[:w:en:Pierre-François Hugues d'Hancarville]] already used by item [[Q2920822]]".
Now if I click the error message on Wikidata it goes to http://www.wikidata.org/wiki/Enwiki:Pierre-François Hugues d'Hancarville, and it should go to http://www.wikidata.org/wiki/w:en:Pierre-François Hugues d'Hancarville.
