    Allow fill_archive to be called with NULL fname.
    
    The fill_archive function should support being
    called with a NULL fname argument. A NULL fname
    argument indicates that the default archive should
    be opened. We enable this by setting ah.fname to
    NULL before initializing ah or calling open_archive.
    This way if fname is NULL then ah.fname remains NULL
    and open_archive opens the default archive.
