Bug ID: 41914
           Summary: incorrect execute path within nested if (else)
                    statement
           Product: Wine
           Version: 1.9.23
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: cmd
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When we execute the following batch command on wine's cmd

if "x" == "a" (
) else (
 echo 11
 if "y" == "b" echo 12
 echo 13
)
echo 20

normally 11 13 20 should be displayed.

but in version 1.9.23 (cmd /version: Microsoft Windows 6.1.7601 (1.9.23)),
it displays 11 20. (13 is skipped.)

Apparently it seems that it jumps to the end of the "else" clause of the outer
"if" when there is no corresponding "else" clause whose inner "if" condition is
false.
