AtomPub return incorrect "edit" link

[tarmes]

The 'edit' URL returned by Wordpress when uploading *images* is incorrect. POSTing the image will return something like this:

<link rel="edit-media"

href=" http://www.myblog.com/blog/wp-app.php/attachment/file/491" />

<link rel="edit" href=" http://www. myblog.com/blog/wp-app.php/post/491" />

The edit media URL is correct, however if I do a GET of the edit URL, to retrieve the metadata, the result is empty. After looking at the source I realised that it should have been returning this:

<link rel="edit" href=" http://www. myblog.com/blog/wp-app.php/attachment/491" />

With this URL the GET works

Added a patch to make sure that media files reference /wp-app.php/attachment/XXXX instead of /wp-app.php/post/XXXX that fixes it both for the media collection listing and the individual entry listing.
