In Commons categories files sorted by default at the letter F, but not at the beginning of filename. But when add defaultsort key images sorted without 'File'.

For example: There are files [[:File:Central stadium in Cherkasy.jpg]], [[:File:Naftovyk Stadium, Okhtyrka.jpg]], [[:File:RSC Locomotive.jpg]], [[:File:Zirka Stadium.jpg]] i category. I want to place RSC Locomotive.jpg at the letter L (and wait to see it between Central Stadium and Naftovyk), when I add {{DEFAULTSORT:Locomotive Stadium, Simferopol}}, I see the file after Zirka Stadium (at the end of category). And now I should add defaultsort to other files in category.
