[PATCH] tree_entry_interesting(): with no pathspecs, everything will match

Hence the function should return "2" in such a case as advertised.

Note that finding a directory that busts the depth limit does not mean non
directories at the same level would also bust the limit (they don't), so
we still need to return 1, not 2 in the within_depth() codepath.

  Thanks.  I'll queue this.
