Indeed.  Otherwise it would be impossible to determine the offset to the 
base object if that base object is not in the pack.

That doesn't mean there isn't any OFS_DELTA left to resolve though.  
But this function is only about adding missing objects to the pack and 
the deltas that need them must be REF_DELTA objects.

Once a REF_DELTA has been resolved with an external object, it then 
constitute a possible new base for remaining OFS_DELTA or 
REF_DELTA objects, and that is found recursively in resolve_delta().
