VersionSpec equivalent of /version:W

Question

What is the VersionSpec equivalent of "/version:W" when used with TF.EXE?

For example, Buck Hodges demonstrated the following usages (from http://blogs.msdn.com/b/buckh/archive/2009/01/26/how-to-determine-the-latest-changeset-in-your-workspace.aspx)

tf history . /r /noprompt /stopafter:1 /version:W

Answer 1

I think it is an instance of Microsoft.TeamFoundation.VersionControl.Client.WorkspaceVersionSpec.

You can't pass empty values to the constructors, so I assume TF.EXE does that automatically
