eval: Make -hidden behave consistently

Previously there was an unexpected difference between

    $ bfs .hidden -hidden

and

    $ bfs ./.hidden -hidden
    ./.hidden

The intent of the code was to avoid considering `.`, the default
starting point, as hidden and thus pruning a whole search with
-nohidden.  Fix it to do that explicitly, and handle `..` too.
