This doesn't look like a bug, rather a feature request, because it works
(and worked in Emacs 22.1) exactly as described in the docstring of
`insert-default-directory', i.e. that non-nil means inserting the
default directory as the initial contents of the minibuffer.
It doesn't say it should prepend the default directory to default
values. And I don't think this would be a good thing to do.
