Bug ID: 40181
           Summary: cmd: Conditional not applied to multiple commands
                    separated by '&'
           Product: Wine
           Version: 1.9.3
          Hardware: x86

                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd

In a batch file, if using a conditional to execute a series of commands
separated by ampersands, only the first command has the conditional applied;
the remaining commands are always run.

Example:

if "A"=="B" echo OK & echo ERROR

Expected results: Nothing is printed.
Actual results: "ERROR" is printed.

Both Windows 7 and Windows 10 have the expected behavior.
wine-1.7.55 and 1.9.3 have the incorrect result.

This affects the batch file used by CTGP-7, a Mario Kart 7 modding utility.
