Yes, I think that's right.

The latest documentation still has this:

   Note: if an element of the alist names a FUNCTION as its cdr, that
   function must return a non-nil list of file-name extensions.  It
   cannot return nil, nor can it signal in any way a failure to find a
   suitable list of extensions.

The end of the first sentence should be "file-names."  Then I think this
bug report can be closed.

Thanks again.
