This might not be a bug, but I couldn't find anything in NEWS regarding
this issue, and it breaks my personal autoload setup.

Recipe:

* mkdir -p ~/foo/bar

* Create a file 'test.el' in foo/bar, containing

  ;;;###autoload
  (defun testthis ()
  )

* cd ~/foo and call

  emacs --batch --eval '(let ((generated-autoload-file "~/foo/loaddefs.el")) (update-directory-autoloads "~/foo/bar")))'

* The file ~/foo/loaddefs.el will have this autoload definition:

  (autoload 'testthis "bar/test" "\

  Using emacs v23.3, I only get

  (autoload 'testthis "test" "\

It's a feature: since foo/bar is not in `load-path', autoload.el figures
that only "bar/test" will properly load the file.
So you just need to set `load-path' to include `foo/bar' like you
probably already do elsewhere.

But it's a new feature, right? Emacs 23.3 doesn't seem to do that.

If it's new, I think it should be mentioned in NEWS; it is an important
change for anyone creating Emacs packages, since I now have to make sure
that `load-path' during autoload-generation and during actual usage of
the package is consistent.

Could you suggest a NEWS entry?  That would be helpful, since I don't
understand how the current autoload behavior breaks your setup.

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.

I went ahead and committed this NEWS entry.
