Sorry, I use other tools, so can't really help you here.
I use msysgit (the official "git for windows" commandline client), it comes with a "git gui" utility which is a somewhat retarded UI that simplifies the basic everyday tasks; it shows the diffs for files being committed. http://msysgit.github.io/
I also have TortoiseGit, but I use it only for merging conflicts. http://code.google.com/p/tortoisegit/
Ad wiki: there seems to be no more supporters of wiki move, so I'd say it's safe to remove it. Bearbin, will you do the honors?
