Thanks.

1. I don't see that we support a nil value, so I think we should add it,
   and `nil` should mean "never time out".  This would be easier to set
   than (setq ispell-help-timeout most-positive-fixnum).

2. I gave this a try, but actually I'm not at all sure why we should
   hide the buffer at all, by default.  The user asked to show it, after
   all, and Emacs is waiting for them to hit a key.  IMO, it is hard to
   even understand the purpose of this hiding "feature".

   I think we should just leave it on the screen, which is what the help
   system does everywhere else.  Users who _really_ want to hide it, for
   some reason that I don't understand, will just have to customize it
   back.  So I'm in favor of a `nil` default.

The above 1-2 should be documented in NEWS.

3. We should probably consider this, because a value <1 is rather
   useless and more likely than not a user mistake:

The :type should be 'natnum instead, and the :version tag needs updating
like Robert pointed out.
