    Ignore index lines without either a '+' or '-'
    
    When upgrading from when a previous release that doesn't have the latest
    VSM index file changes, the utilities will assert when trying to parse the
    index file from the previous version. Fix that by ignoring lines not
    starting with either '#', '+' or '-'.
