subrepo: allow a representation of the working directory subrepo

Some code cannot handle a subrepo based on the working directory (e.g.
sub.dirty()), so the caller must opt in.  This will be useful for archive, and
perhaps some other commands.  The git and svn methods where this is used may
need to be fixed up on a case by case basis.
