Summary: cmd's attrib command doesn't accept multiple
                    attributes
           Product: Wine
           Version: 1.3.25
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: cmd
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

And it doesn't do the right thing with "attrib +r" or "attrib +s +r".

Here's a draft patch for this.  Not yet finished.
