The new Nautilus file extraction always creates a parent directory with name of archive. It can be considered not to create a parent directory on certain occasion.

That is, when the archive contain only one directory and all files are within the directory, don't create a parent directory.

Eg:
1. Download the file: http://ftp.gnome.org/pub/GNOME/core/3.22/3.22.1/sources/yelp-tools-3.18.0.tar.xz
2. Extract the file using right click -> Extract here

The following is the tree view of the output:
.
└── yelp-tools-3.18.0
    └── yelp-tools-3.18.0
        ├── aclocal.m4
        ├── AUTHORS
        ............

When extracted with 'tar xf yelp-tools-3.18.0.tar.xz' the following is the tree view:
.
└── yelp-tools-3.18.0
    ├── aclocal.m4
    ├── AUTHORS
    ............

So when parent directory has the same name as the only child directory, avoid creating the parent directory. (Do the same way as the 'tar' output above)

Sorry for being verbose. :-)

Thanks.
