Small cleanups, untested

Here's another idea I'm not going to pursue. What palindromize() does is a variation of the standard problem of finding minimal edits that convert one string to another: just ignoring case and adjusting for one string being reversed. So I would use an existing library function (hopefully) or code up a standard diff algorithm (with a pointer to whichever one I choose).
