example_batch_file.cmd

The attached batch file shows on windows the lines A B.
But wine gives this output:
----
$ LANG=C wine64 example_batch_file.cmd

C:\>if 0 == 0 echo A& (if 0 == 0 (echo B) else (echo C))
A
B
C
Can't recognize ')' as an internal or external command, or batch script.

This isse was found during investigation to bug #53155, which leads
to an endless loop in this batch file:
