In-Reply-To: <m27j093b0l.fsf@gaston.none> (message from Wolfgang Jenkner on Tue, 12 Sep 2006 07:32:42 +0200)

    I think what you call the `second change' is making C-u C-c SPC work.

Yes.

    I meant the part where I remarked that, e.g., `find-file-at-point'
    uses `current-prefix-arg'.  A call to `conf-space-mode' while
    'find-file-at-point' is being executed may still see the same prefix
    argument which was passed to `find-file-at-point'.

Now I see the problem you mean.

Now that I think about it, this whole approach is wrong.  It is wrong
to look at current-prefix-arg except inside of an interactive spec.

Does this patch make it all work?
