This started by me wanting something like what the last patch does. That wasn't too hard, except we had no strcasestr(), and also our regex engine (which I didn't really want to pull into the mix anyway) doesn't have a flag that requests case-insensitive matching. So I wanted to add strcasestr(), but then I stumbled on a bunch of stuff that should be cleaned up in str-land.
The first five patches are logically independent of each other. The last three do depend on each other, and the last patch also depends on patch 2.
