Current Directory and Parent Directory returned by ListDirectory.

Running sftpClient.ListDirectory(path) returns values . and ...
Whilst this is valid behaviour, special consideration has to be given whenever using this command to determine if we want these "relative-folders". There's also no flag (e.g. IsRelative) to easily filter; rather we have to filter on the folder's name to detect / exclude these.

$client.ListDirectory('/files') | Format-Table Name, Is* -AutoSize

Adding an option to hide these (either on the call to ListDirectory, or as a preference for the SftpClient itself would be helpful; or simply providing an IsRelative property on the SftpFile class to allow easy discrimination.

Comienza en el punto de entrada ListDirectory e inspecciona la representación de SftpFile mostrada por el issue. Compara la opción de filtrado solicitada con un discriminador de estilo IsRelative y verifica después que el comportamiento elegido permita a los llamadores excluir . y .. sin filtrado basado en nombres. Se considera completado cuando la API expone una forma documentada y comprobable de ocultar o identificar ambas entradas.
