Followup of T235263: Make it possible to bypass automatic redirection to exact matches in commons:
Before T235263 typing w: into the commons search box led directly to wikipedia. Now type "w:" to Commons search box, it will go to https://commons.wikimedia.org/w/index.php?search=w%3A&title=Special%3ASearch&go=Go&ns0=1&ns6=1&ns12=1&ns14=1&ns100=1&ns106=1 with no link to Wikipedia.
Before T235263 typing "COM:VP" into the commons search box led directly to the commons village pump. Now it goes to https://commons.wikimedia.org/w/index.php?search=COM%3AVP&title=Special%3ASearch&go=Go&ns0=1&ns6=1&ns12=1&ns14=1&ns100=1&ns106=1
This ticket is to re-instate the old behaviour for search strings beginning with namespace or interwiki prefix
