py-pathspec: updated to 0.8.0

0.8.0:
- Expose what patterns matched paths. Added `util.detailed_match_files()`.
- `match_tree()` doesn't return symlinks.
- Add `PathSpec.match_tree_entries` and `util.iter_tree_entries()` to support \ 
directories and symlinks.
- API change: `match_tree()` has been renamed to `match_tree_files()`. The old \ 
name `match_tree()` is still available as an alias.
- API change: `match_tree_files()` now returns symlinks. This is a bug fix but \ 
it will change the returned results.
