The plural magic word is exposed in MediaWiki:Pagetriage-characters-left. I found this bug by going to NtTerminalProcess via PageTriage on en.wikipedia, then I used the "Mark this page as reviewed" option in the curation toolbar and started typing. Once I had typed in the first letter the message was "{{PLURAL:249|249 char|249 chars}} left"
The expected behaviour here is to show "249 chars left".
...Apparantly the plural magic word is also shown under the option "Send appreciation", in the same way.
Version: unspecified
Severity: trivial
