    Ignore empty elements in the search path
    
    We were treating empty elements in the search path as meaning the
    current directory. However, empty elements are easy to end up with
    by mistakes in path construction, and treating them as the current
    directory can result in extremely confusing results. If the current
    directory is actually meant, it can be specified as '.'.
