Using a MediaWiki message as a raw regular expression
isn't safe; a
broken expression could break the wiki in annoying ways. Additionally
the message lookup required message cache initialization which doubled
the runtime of cached page views. The hardcoded linktrail in the
language files is now used for security and performance reasons.
OK, thanks, it works fine now.
I've updated ru, cs, and fr as requested.
Well, our language file would need much more than this small update,
but thanks anyway.
