The indirect buffers is really cool. I'm fixing up the
unfinishedness in the `searching.texi' where I editted it when we
added the regexp patches for `*?' and `\(?:'. To explain better, I'm
writing a short code example. It really neat to type the code in one
window narrowed and set to emacs-lisp mode, and have it appear in the
texi window too. :-) Way cool.
