Here's a suggestion:

When generating autoloads, `update-directory-autoloads' now longer
assumes that every inspected file will be in your `load-path', but will
now generate relative names according to your current `load-path' setting.

Stefan, please correct me if this is not a proper description of the new
behavior.  Also, I'm not sure if this new feature only affects
`update-directory-autoloads', but also other autoload functions.
