When visiting a page like this:
http://en.wikipedia.org/wiki/Special:Blockip/100.100.100.100
I think it would be useful to have a link to the user and user talk page for the user (or IP) in question from the Blockip page. It can be done by checking what comes after "Blockip/" is a single IP or a user account, and providing the links accordingly (no such links should be given when an IP range is provided).
Before providing a patch for this bug, I'd like to have your comments about the idea.
