           Summary: Wine cmd handles incorrectly if-for on a single line
           Product: Wine
           Version: 6.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED

Wine cmd handles incorrectly expression with if and for on a single line if the
condition is not met such as:

if not ""=="" for %%i IN (A) DO (echo %%i)

Can't recognize 'DO ' as an internal or external command, or batch script.

See attached test case.
