Hm...  I just tried replacing completing-read with the ido method, and
I got a backtrace.  So it wants a list instead of an obarray, but that's
easily enough fixed:

But I wonder if that's the wrong way to do it.  Wouldn't it make more
sense for the user to say

(ido-mode '(buffer file gnus org))

and then for Gnus to look at the ido-mode variable?  This requires a
change in ido-mode, of course, but doesn't it seem like a more clean way
for all the various packages to integrate with ido?

I've crossposted this to the Emacs list for feedback.
