Thanks for your patch, applied with r23368.

For your information:

5 messages of 1630 in ru don't use some variables while en uses them:

• cascadeprotected
• cascadeprotectedwarning
• revdelete-selected
• logdelete-selected
• protect-cascadeon

Thanks, yes i know

But russian ConvertPlural is not appropriate for these messages

Oops, I remember you wrote this in the past, sorry.

But isn't it possible to translate these messages in another way to use these variables? I do not speak Russian so sorry if this is a dumb question.

We need more complicated Russian convertPlural function to use these variables. (See bug 10008)

But I think it is not obligatory, variables are not important in these messages.

Example:

'cascadeprotected' => 'This page has been protected from editing, because it is included in the following {{PLURAL:$1|page|pages}}, which are protected with the "cascading" option turned on:',
