I just wanted to clarify this, as Robert points out I wasn't sufficiently clear
with one of the details.

It's not that some files aren't going to have digests anymore, but that the
digests are going to be in the VCS rather than explicitly in the Manifest.
Portage does explicitly need support for the changes, but that was inherent to
the idea of using slim Manifests for the main repository, long before overlays
are used.

Existing design:
1) Manifest:
   DIST - digest of distfiles located in DISTDIR
   AUX/EBUILD/MISC - digest of files located in the tree

New Design:
1) slim Manifest:
   DIST - digest of distfiles located in DISTDIR
_AND_
2) VCS index:
   SHA1/* digest of files located in the tree

BOTH sources must be present. A slim Manifest would not be valid without the
VCS containing digests of the files not contained in the Manifest.
