Why does this need a particular class?  VirtualVersionedFiles provides
the right amount of abstraction, IMHO.  You can just implement get_lines
on it.

And I also think that this is layered badly.  Repositories are meant to
be provided on top of VersionedFiles, so implementing VersionedFiles on
top of Repository is a recursive definition.
