Re: propose adding Icicles to Emacs

[Richard Stallman]

    Redefining completing-read is a no-no in my book.  Please try to rewrite
    your code so as not to do that (e.g. using minibuffer-setup-hook).  Also, if
    it turns out to be impossible, or very inconvenient, then post a request for
    enhancement to make it possible/easier.

We can make changes in completing-read so as to accommodate the needs
of these features.  The point is to do this cleanly.
