Personally, I prefer to _always_ initialize, just to prevent conditional
codepaths from being added later that break formerly working code. I
think this is probably why I went through and tried to initialize all of
the hashes when I first created the patch. I don't like it when a
variable is defined here and then used more than a screen's worth later,
because you can miss stuff like this.

Thankfully, 3 and 4 are very minimal changes. Good catch!
