Bug #: 33636
           Summary: wine cmd: invalid behaviour of '&' operator
           Product: Wine
           Version: 1.5.29
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Commands after '&' is executed, even under negative 'if'.

if "0"=="1" echo 1 & echo 2

Will output "2", but must not output nothing, because this line is equivalent
to

if "0"=="1" (
    echo 1
    echo 2
  )
