Right, as discussed in the commit message. -Peff

We give several helper config examples, but don't make clear that these are raw values. It's up to the user to add the appropriate quoting to put them into a config file (either by running with "git config" and quoting against the shell, or by adding double-quotes as appropriate within the git-config file). Let's flesh them out as full config blocks, which makes the syntax more clear (and makes it possible for people to just cut-and-paste them as a starting point). I added double-quotes to any values larger than a single word. That isn't strictly necessary in all cases, but it sidesteps explaining the rules about exactly when you need to quote a value. The existing quotes can be converted to single-quotes in one instance, and simply omitted in another for simplicity (unless you have odd whitespace in your password, the shell whitespace-splitting behavior is fine). I also swapped out backticks for our preferred $().
