Rails - May 2006 - file_column, image_tag, absolute paths?

The docs in the SVN version of file_column state that url_for_file_column
will return paths relative to the application root, and that if I pass it
to image_tag, I''ll get an absolute URL.

This doesn''t appear to be the case, at least with Rails 1.1.  image_tag
returns the same app-root-based path that it''s given.

Doc bug?  Rails change?  file_column bug?
