  get_dep().end() is the proper way to test for whether a dependency is
valid.  For dependencies constructed with the default constructor, it
should return an end iterator.  Unfortunately, this got broken when the
universe layer was rewritten to conserve memory.  Easy to fix, though:
just have end() check or a NULL cache.
