About [[MediaWiki:Massmessage-summary-removemulti/en]]
Fragment of a discussion from Translating talk:MediaWiki
This also applies to Massmessage-summary-addmulti ("Added $1 {{PLURAL:$1|page|pages}}"). If these messages only kick in when 1+ pages are added/deleted then documentation should say this (and it might still be pedagogic to add the singular case in English)
