Re: propose adding Icicles to Emacs

[Richard Stallman]

    I might add that once you have the ability to type and change the regexp to
    match dynamically, there is less raison d'etre for these
    `customize-apropos-*' commands. An Icicles user would simply use
    `customize-face' and so on, instead.

With `customize-apropos-faces', you get a custom buffer with ALL the
faces whose names match the regexp.

Using `customize-face' as a multi-command, and regexp-based
completion, you can pick some of the matching faces and put each of them into
a custom buffer.  But you can't make a custom buffer with two of them,
or all of them.  (Am I mistaken?)

This suggests that `customize-face', when it uses the multi-command
feature, should put all the faces in one buffer.  Well, I think that
is not too hard to do, in my proposed framework.

But this suggests there should be a minibuffer command to say "submit
each of current candidates, one by one."
