Make 'make clean all' work

In this case, the 'clean' step would nuke the metadata files, but they have
already been read, so in-memory state is fine.  This triggered a couple of
pathological conditions that would not normally be hit.  This commit fills in
those nodes in the DAG, even though they are not directly needed in most
builds.

Also fix some whitespace for readability.
