Uppity風に賢く上位ディレクトリに移動するプラグイン
== Command ==

:goParent
    賢く上位ディレクトリに移動します

== Sample ==
:goParent を実行するごとに下記のように移動します
  - http://www.example.com/path/to/file.txt?query=value#anchor
  - http://www.example.com/path/to/file.txt?query=value
  - http://www.example.com/path/to/file.txt
  - http://www.example.com/path/to/
  - http://www.example.com/path/
  - http://www.example.com/
  - http://example.com/
挙動はUppity( http://trac.arantius.com/wiki/Extensions/Uppity )を参考にしています
