My main issue was that I needed to join arbitrary strings and then split
them, which is why I URL-encoded them (so that they would no longer
contain spaces) and then used spaces as the "join" separator. With
Josh's suggestion, I wouldn't need any sort of encoding or quoting, so I
think I'll use that.
